The first part provides a brief description of the historical background of ecological activities in China and their major achievements in the past. The second part is a comprehensive review of various types of ecological control activity aimed at the improvement of natural and artificially established ecosystems at the landscape,regional(watershed) and higher levels. The scope of and differences between some ecological terms used in China such as ecological protection, conservation, remediation(rehabilitation), restoration as well as the reestablishment of new ecosystems are elaborated. The review suggests that the term "ecological conservation and construction"should be used to embrace all types of ecological control activity in China. Finally, five guidelines are proposed for promoting the implementation of ecological conservation and construction in China based on the two important governmental documents related to the development of ecological civilization in China.展开更多
