Municipal engineering refers to the construction of municipal facilities. Municipal facilities refer to various buildings, structures, and equipment that are set up within the planning and construction scope of urban areas and towns (townships) to provide residents with paid or unpaid public products and services based on the responsibilities and obligations of the government. Municipal works mainly includes: urban public utilities such as urban roads, bridges, water supply and drainage, sewage treatment, urban flood control, gardens, road greening, street lamps, and environmental sanitation. The project management of China’s municipal engineering has gone through more than 20 years, and a project management mechanism with modern management significance has been formed. However, there are still many problems and deficiencies, especially in the context of the gradual improvement of China’s market economy in recent years, it is necessary to constantly innovate and explore the construction management mode of modern construction engineering projects with Chinese characteristics to meet the needs of the development of the market economy.
This book is mainly described in two parts. The first part mainly explains the construction technology of road engineering, and the second part mainly explains municipal engineering projects management, hoping to help the work of related staff.

市政工程是指市政设施建设工程，市政设施是指在城市区、镇（乡）规划建设范围内设置、基于政府责任和义务为居民提供有偿或无偿公共产品和服务的各种建筑物、构筑物、设备等。市政主要包括城市道路、桥梁、给排水、污水处理、城市防洪、园林、道路绿化、路灯、环境卫生等城市公用事业工程。我国市政工程的项目管理已走过了二十几年的历程，形成了具有现代管理意义的项目管理机制，但还存在很多问题和不足，特别是在近几年我国市场经济逐步完善的情况下，更需要不断创新，探索有中国特色的现代建设工程项目施工管理模式，以适应市场经济发展的需要。
本书主要从两篇内容进行叙述，上篇主要对道路工程类的施工技术进行阐述，下篇主要对市政工程项目管理进行说明，希望能够有助于相关工作人员的工作进行和开展。

With the continuous progress of society, cities are self-contained in political economy and cultural transportation, but they are not independent of each other, and there is a close relationship between them. Municipal engineering plays an important role in the regulation. The main task of municipal engineering is to make full use of the available planes and spaces according to the overall layout of the city, and to consider the greening public facilities of the garden, so as to speed up urban development, reduce investment, and improve the city’s overall competitiveness. The construction of municipal roads is an important part of municipal engineering, and drainage engineering is the top priority. Therefore, in municipal roads, the work of water supply and drainage engineering is very important. At the same time, there are many problems that need to be solved, which need the joint efforts of professionals.
This book is divided into nine chapters to elaborate and analyze municipal roads and water supply and drainage engineering in a comprehensive manner, to solve the problems raised, and hope that it can be used to help the project development of related staff.

伴随着社会的不断进步，城市在政治经济方面和文化交通等方面都自成体系，但也不是相互独立的，他们之间有密切的联系。而市政工程在其中起着重要的调节作用，市政工程的主要任务就是根据城市的总体布局，将所拥有的平面以及空间充分地利用起来，把园林的绿化公共设施也考虑进来，加快城市发展的步伐，减少投资，提高城市的综合竞争力。市政道路的建设是市政工程的重要组成部分，而其中的排水工程更是重中之重。因此在市政道路中，给排水工程的工作是非常重要的，同时，需要解决的问题也很多，需要专业人员共同努力解决这些问题。
本书分九章内容对市政道路与给排水工程进行详细全面地阐述与分析，对提出的问题进行解决，希望能用对相关工作人员的项目开展有一定的帮助。

With the continuous improvement of people’s life and urbanization level, the urban construction and environmental construction in our country are advancing at an unprecedented high speed. There is an upsurge of landscape architecture design all over the country. Landscape architecture construction has become an important part of urban construction.
     There are seven chapters in the book. The first part of the book introduces the construction and future of landscape architecture and the current situation and trend of the development of landscape architecture. The last six chapters focus on the detailed contents of landscape architecture foundation, landscape architecture design, scenery landscape architecture design, landscape architecture design, landscape architecture construction technology and landscape architecture construction project management. It makes outstanding contributions to the improvement of landscape design concept and construction technology, and also provides a practical reference book for the majority of landscape workers.

随着我国人民生活及城市化水平的不断提高，我国的城市建设和环境建设以前所未有的高速度向前推进，全国各地都出现了风景园林建筑设计的热潮，景观园林建设已经成为城镇建设的重要内容。
      本书共七章，开篇绪论部分简单介绍了风景园林景观建设与未来和园林建筑发展现状与趋势的大概情况，后六章重点阐述了风景园林基础、园林景观设计、风景园林景观设计、风景园林建筑设计、园林建筑施工技术与园林建筑施工项目管理的详细内容，为我国园林景观设计理念与建筑施工技术的提高做出突出贡献，也为广大园林工作者提供了一本切合实用的参考书。

With the development of industry, air pollution is serious and respiratory diseases are increasing day by day, so it is necessary for hospitals to set up respiratory department. Respiratory diseases are mainly divided into the following categories: pulmonary infection, pulmonary manifestations of systemic diseases, diffuse pulmonary diseases, chronic obstructive pulmonary diseases and asthma, pulmonary circulation diseases, disorders of ventilation regulation, rare pulmonary diseases, acute respiratory distress syndrome, mechanical ventilation and respiratory monitoring, lung cancer, etc.
This book first summarizes the basic theory and diagnosis of respiratory medicine and respiratory diseases, and then dialectically diagnoses and treats the above respiratory diseases. The contents of the book are comprehensive, rich and practical, which is instructive and can be used as a reference for medical staff, especially respiratory professionals.
As this book covers a lot of contents and involves a lot of knowledge, the format, depth and breadth of the contents of each chapter may not be the same, and fallacies are inevitable. Readers are welcome to criticize and correct it.
