STUDY ON STRATEGY OF ECOLOGICAL AND ENVIRONMENTAL CONSTRUCTION IN XINJIANG

Water is key factor to influencing change of environment or advanced ecological process. The ecosystem of vegetation is both nursery and consumer of water resources in arid areas. The courses of regulation to water in mountain vegetation systems (forests and grassland) and consumption by natural oasis ecosystem play a significant role for human beings. The strategy of water using to promote ecological environment should persist on a whole and perfect idea, i.e. underground water, running water and river water, are not resource water only, all are very important natural resources, and should be utilized effectively. The water of melted snow (in northern region of Xinjiang) and heavy rainfall (in all parts of Xinjiang) was not paid enough attention in Xinjiang before the Great Western development launched by central government of China. The former can be effectively used by Haloxylon sp. for their regeneration and some short life plants in season of spring, latter can be used by any plants in catchement system. The principles of protecting, promoting and motivating should be held on in ecosystem construction. Three kinds of ecological engineering should be carried out in Xinjiang, these are engineering of establishing functional reserves, engineering of ecosystem renovation, and engineering of ecosystem enhancement. The engineering of establishing functional reserves was newly suggested by State Bureau of Environmental Protection, which protects national ecological security. The engineering of ecosystem renovation is to help natural ecosystem recovery from suffered status. The last engineering is to establish some new ecological engineering according to needs of economics development. The effective coalescence of ecological process and economic process is main goal of modern ecological construction. According to needs of ecological engineering construction, a series researching works should be done in various region of Xinjiang.
