In order to meet the needs of urban economic development, we must promote the soundness of the landscape planning system, ensure the effective coordination of its internal links and strengthen of its planning efforts through the deepening of its planning model, so as to ensure the stable development of urban image engineering, meet the needs of people for the quality of daily life, promote the positive improvement of urban ecological environment and the soundness of modern urban planning systems, and meet the needs of practical work.

The planning of modern urban garden landscapes should be based on the protection of the urban ecological environment, using all available spaces in the gardens to increase the urban green area, so as to promote the improvement of the urban comprehensive environment and the people’s living comfort. This requires modern urban garden landscape designers to integrate the urban basic information and basic garden conditions, focusing on native plants, humane, novel but not impetuous, beautiful and practical, simple and satisfying needs. Urban gardens that meet ecological requirements are the principles and goals of garden planning and design.

The construction of urban landscape should be synchronized with the process of urbanization, and it is a sign of the development of urban civilization. It plays an important role in improving the living environment of the citizens, beautifying the urbanization environment and improving the happiness of the citizens. In the planning of urban landscape, we should adhere to the principle of people-oriented, pay attention to the design concept of adapting to local conditions and diversifying, avoid the uniformity of urban landscapes and copying each other, prevent urban landscapes from becoming government image projects, and promote the urban landscape to play its due role in the city.

为了满足城市经济的发展需要，我们要促进园林景观规划系统的健全，通过对其规划模式的深化，确保其内在环节的有效协调，促进其规划力度的加强，以保障城市形象工程的稳定发展，满足人们对于日常生活质量的需要，促进城市生态环境的积极改善，促进现代城市规划系统的健全，满足实际工作的需要。

现代城市园林景观的规划要以城市生态环境的保护为基础，利用园林内一切可以利用的空间，提高城市绿化面积，以此促进城市综合环境的改善，提高人们居住的舒适度。这就要求现代城市园林景观设计人员要以综合城市基础信息与园林基本情况，以本土植物为重点，人性化、新颖而不浮躁、美观而实用、简单而满足需求，符合生态要求的城市园林是园林规划设计的原则和追求的目标。

城市园林景观的建设应该与城市化的进程是同步的，是城市文明发展的标志。对于提升市民的居住环境，美化城市化境，提升市民的幸福感都有着重要的作用。在城市园林的规划中要坚持以人为本的大原则的前提下，注重因地制宜，多样化的设计理念，避免城市园林景观千篇一律，互相照搬照抄的问题出现，避免城市园林景观成为政府的形象工程，促使城市园林景观在城市中发挥它应有的作用。

Garden planning and design is an ancient and young discipline in China. It is said to be ancient because the history of gardening can be traced back thousands of years, and there are a lot of examples and theories of traditional gardens in the world. However, due to the development and evolution of this discipline in practice, it is both an integration with modern society and a matter of recent decades.

Before the 1980s, there were few people in the garden planning and design industry. National power is limited. Except for individual outstanding works, it is still at a relatively basic level. Generally speaking, axes, scenic spots, landscaped greenery, and traditional or innovative garden architectural symbols have become common patterns in garden planning and design. The image of the park in people's minds is basically a pavilion under the shade of green.

Since the 1990s, economic development and urbanization have brought about the prosperity of urban garden planning and design in China. With the gradual improvement of urban functions, parks, green squares, ecological corridors and suburban scenic spots have become the modern symbol of the city and the inevitable way to improve the quality of urban environment, life and culture. The functional positioning of urban garden ecology, landscape, culture, rest and risk reduction has been gradually recognized by the industry. From traditional gardens to urban greening and suburban integrated landscape, the concept of landscape planning and design is gradually deepening and improving, and the field is also expanding. On the basis of the traditional culture, the designers constantly combine the national conditions in practice, absorb some new thoughts and ideas from abroad, and adapt to the needs of modern life to create a batch of better works. Landscape architects not only lead the landscape planning and design, but also participate in the overall urban planning to intervene in urban design from a larger and wider level.

Modern landscape planning and design must innovate the concept of planning and design, actively absorb the advanced experience and technology of foreign landscape planning and design, and combine the cultural characteristics and local customs of this region to design excellent landscape art works. At the same time, the planning and design of modern landscape gardens should give full play to their ecological, cultural and economic functions to create a good ecological environment for promoting the sustainable development of modern cities.

园林规划设计在我国应该说是一门古老而又年轻的学科。说它古老，是因为我们的造园史可以追溯到几千年前，有一批在世界上堪称绝佳的传统园林范例和理论。说它年轻，是由于这门学科在实践中发展、演变，既与现代社会融合接轨，又是近几十年的事。

20世纪80年代之前，园林规划设计业内人士很少，加上国力有限，除了出现过个别优秀作品外，总体上还处于比较初级的水平，一般地讲，轴线、景区、山水绿地，加上传统的或革新式的园林建筑符号，成为园林规划设计的普遍模式。人们心目中的公园形象，基本上是绿荫下的亭台。

20世纪90年代以来，经济发展了，城市化的进程带动了全国城市园林规划设计的繁荣随着城市功能的逐步健全，公园、绿化广场、生态廊道、市郊风景区等愈加成为了城市的现代标志，成为提升城市环境质量、改善生活品质和满足文化追求的必然途径，城市园林生态、景观、文化、休憩和减灾避险的功能定位逐步被业内认同，从传统园林到城市绿化，再到城郊一体化的大地景观，园林规划设计的观念在逐步深化和完善，领域也在拓宽。设计人员在实践中不断结合国情，在继续从传统文脉中吸取营养的基础上，吸纳国外的一些新思潮、新理念，顺应现代生活的需求，创造了一批较好的作品。风景园林师不仅主导着园林规划设计，还参与城市总体规划，介入城市设计，从更大更宽的层面上发挥作用。

现代景观园林规划设计必须创新规划设计理念，积极吸收国外景观园林规划设计的先进经验和技术，结合本地区的文化特色和风土人情，设计出优秀的景观园林艺术作品。同时，现代景观园林规划设计还要充分发挥其生态功能、文化功能和经济功能，为推动现代城市可持续发展创建良好的生态环境。

Landscape engineering is to beautify the environment within a specific range. It is very scientific and artistic. Landscape engineering is the reasonable construction in the region of green space or landscape architecture. The development of garden engineering is related to the development of regional economy, environment and culture.

Since the reform and opening up, with the rapid development of social economy and the acceleration of urbanization, various environmental problems have gradually emerged. At the same time, the improvement of material and cultural living standards also puts forward higher requirements for spiritual needs. People's desire for nature and pursuit of beauty have promoted the further development of the garden industry. Gardening is not only a discipline, but also an art. The landscape is divided into two categories, namely natural landscape and human landscape. Natural landscapes, such as land, rivers and oceans, were created before man. After human civilization, human landscape is a kind of landscape which has been transformed by nature and injected with human will and activity. From an aesthetic point of view, the garden landscape art comes from nature and life. In life, the pursuit of beauty has never ceased, and mankind achieves this goal through the creation of art. Under normal circumstances, people tend to pay more attention to the formal beauty of garden landscape. The beauty of garden landscape comes from its artistic creation. When people appreciate and evaluate the beauty of garden, they focus on its artistry. However, the development of the garden industry is not perfect. There are many problems. How to develop systematic and modern landscape architecture with Chinese characteristics requires us to think systematically about the present situation and future development of landscape engineering.

Facing the reality of the ever-changing project construction, this book introduces the concept, design, construction, management, landscape art and its application of garden engineering. Combined with the latest technology and concept of modern garden engineering construction, this paper analyzes this problem systematically and comprehensively, and puts forward basic and effective solutions and scientific principles to provide reference for the majority of garden workers. This is our intention to write this book. As the book contains more content, involves more cumbersome knowledge, and has more compilers, the format, depth and breadth of the contents of each chapter may not be inconsistent; and the fallacies are inevitable. Readers are invited to criticize and correct. Suggestions for improvement will be gratefully received.

园林工程就是美化坏境，是在特定范围之内，非常具有科学性和艺术欣赏价值，合理建造于本地域的绿地或风景建筑。园林工程的发展关系着地区经济、环境和文化的发展。

改革开放以来，伴随着社会经济的飞速发展，城市化进程的加快，各种环境问题也逐渐露出端倪。与此同时，人们物质文化生活水平的提高对精神需求也提出更高的要求，人们对自然的渴望与美的追求催生了园林产业的进一步发展。园林不仅是一门学科，一项事业，也是一门艺术。景观分为两大类，即自然景观与人文景观。自然景观产生于人类之前，如土地、河流、海洋等；人文景观产于人类文明之后，它是经过对自然的改造，被注入人类意志和活动的一类景观。从美学的角度来看，园林景观艺术来源于自然和生活。在人们的生活中，从来没有中断过对美的追求，也从来没有间断过以艺术的创造来达到这一目的。在通常的情况下，人们对园林景观的感受往往更注重它的形式美感。园林景观的美感来自它的艺术创作，当人们在欣赏和评价园林的美感时，着重谈到的就是它的艺术性。然而园林行业发展还不完善，存在许多问题，如何发展具有中国特色的体系化、现代化的风景园林，就需要我们对园林工程的现状及未来发展有系统的思考。

面对日新月异的工程项目建设实际，本书分为园林工程的概念、设计、施工、管理与园林景观艺术及其应用两部分、六个章节的内容，结合当今园林工程建设最新技术与理念，系统全面的回答了这一问题，且提出基本有效地解决方案及其科学原理，希望可以为广大园林工作者提供参考，这也是我们编写这本书的用意所在。由于本书包罗内容较多，涉及知识较烦琐，各章节内容的格式、深度和广度可能并不一致，且谬误无可避免，敬请广大读者批评指正。

After the 20th century, the production of electricity mainly depends on thermal power plants, hydropower stations and nuclear power plants. Tidal, geothermal and wind power are also used to generate electricity where conditions permit. The transmission and distribution of electrical energy is mainly achieved through high and low voltage AC power networks. As the development direction of transmission engineering technology, its emphasis is on researching UHV (over 1 million volts) AC transmission and DC transmission technology to form a larger power network; meanwhile, it is also necessary to study the technical problems of superconductor power transmission. The large-scale power system emerged in the 20th century integrated power generation, transmission, substation, distribution and electricity consumption into an organic whole. It has become a physical engineering system with the widest span of space, strict coordination of time and extremely complicated division of labor.

Since the 1880s, electric power has gradually replaced the steam engine, the technological symbol of the industrial revolution in the 18th century, and become the technological basis of the material and spiritual civilization of modern society. In the past 30 years, HVDC transmission technology has made rapid progress and has been widely used in some transmission fields.

This book is divided into eight chapters to analyze and elaborate the power engineering technology in detail, and the content is comprehensive. We hope this book will be helpful to the related work.

20世纪以后，电能的生产主要靠火电厂、水电站和核电站。有条件的地方还利用潮汐、地热和风能来发电。电能的输送和分配主要通过高、低压交流电力网络来实现。作为输电工程技术发展的方向，其重点是研究特高压（100万伏以上）交流输电与直流输电技术，形成更大的电力网络；同时还要研究超导体电能输送的技术问题。20世纪出现的大型电力系统将发电、输电、变电、配电、用电诸环节综合为一个有机整体，成为社会物质生产部门中空间跨度最广、时间协调严格、层次分工极复杂的实体工程系统。

从19世纪80年代以来，电力已逐步取代了作为18世纪产业革命技术标志的蒸汽机，成为现代社会人类物质文明与精神文明的技术基础。近30年来，高压直流输电技术进步很快，并在一些输电领域内得到了愈来愈广泛的应用。

本书分八章内容对电力工程技术进行详细的分析与阐述，内容全面，希望能够有助于相关工作的开展与进行。
