Other AbstractThe dry-hot valley of Jinsha River is one of the most fragile zones of ecological environment in China, and also is the key district of preventing and curing heavy soil and water loss of the upper reach of Yangtze River. The Jinsha River Valley District has faced with the severe eco-environmental problems, dense population, stricken poverty as well as the negative and pervasive human influence these days. Supported by China's National Key Technologies Research and Development Program in the 10th Five-Year Plan (2001BA901A40), the biological resources development in Panzhihua City and Yuanmou Country is studied. The paper is initiated to use the rich resources of light and heat in the dry-hot valley of Jinsha River to choose the biological resources with both ecological and economic benefits and to do research on the integration of the biological resources development and eco-environmental construction and to construct the theoretical system and use it to the district according to the programs of "Development of West China" and the inversion from cropland into forest land and grass land and the desiderative transformation of economic development in Panzhihua City. ( 1 ) . The investigation of the current biological resources development and eco-environmental construction in the dry-hot valley of Jinsha River, The current ecological environment in the district is described, its general biological resources, development and problems are summarized, and the studies we should pay more attention to are put forward and can provide scientific evidence of biological resources development and eco-environmental construction systematically. (2) . Discussion of the assessment index system of biological resources development and eco-environmental construction in the dry-hot valley of Jinsha River. On the basis of actual condition of the district, the appropriate appraisal of the target system is determined by fuzzy comprehensive evaluation method, which is in favor of carrying through biological resources development and eco-environmental construction scientifically, reasonably and efficiently. (3 ) . Taking azadirachta indica as the experimental object, the paper researches into initial stages of biological resources development in the valley and analyzes the adaptability, influencing factors and eco-environmental benefits and at last points out some suggestions for the development of azadirachta indica in the district. Thus elementarily demonstrates both scientificness and correctness in the assessment index system of the valley.
