       为更好地发挥经营活动分析的作用，本文从经营活动分析的基本概念入手，着重探讨石油销售企业经营活动分析的总体把握，探究石油企业经营管理过程中出现的问题以及对策，并使得分析向经营管理各环节延伸，更好地发挥经营活动分析支持决策和促进管理提升的重要作用。

The development of human economy and culture is inseparable from the construction of ecological civilization, especially the construction of ecological forestry, which is mainly based on forest or forestry. With the rapid progress of human civilization and the rapid development of industry and economy, it not only promotes the progress of human history, but also has a very serious impact on the natural environment. The most prominent performance is the current worldwide ecological crisis, as well as the resulting survival crisis and other fundamental problems. Through the construction of ecological forestry, we can fundamentally improve and solve this problem. Therefore, countries all over the world pay more and more attention to the construction of ecological forestry and promote the sustainable development of the earth. China also regards the construction of ecological forestry as an important part of national construction. At the same time, China has issued various policies to promote the sustainable development of ecological civilization, and continuously increased investment, especially in the development of ecological forestry.
     This book mainly analyzes the construction and management of forestry ecological engineering from six chapters, hoping to contribute to the promotion and development of forestry in China.
