Climate change characteristics and its ecological effects on Huangfu - chuan Basin
Climate change, superimposed on the other impacts on structure and function of fragile ecosystem. natural driving force and human activity, are the major Using statistical methods and NPP mathematical model, climate data in Huangfu -chuan basin and Statistical Yearbook data in Zhungeer County from 1961 to 2010 were used to analyze the characteristics of precipitation, temperature and their ecosystem effects. The results were as follow： precipitation and temperature in Huangfu -chuan basin showed significant seasonal and inter -annual fluctuations; Inter - annual variation of precipitation was not significant, while temperature rose significantly; Mainly affected by the inter - annual fluctuation of precipitation, the inter - annual fluctuations of both NPP and grain production of agro - ecosystem were significant; The change trend of NPP was not obvious, as a naturalsocial - economic complex system, grain production growth of agro - ecosystem was evident, but climatic warming and drying may led to agro -meteorological disasters. In addition, the big fluctuation and poor stability of climate exacerbated land desertification. Therefore, in the process of ecological construction and environment treatment, comprehensive engineering, biological and agricultural measures should be used to reduce the adverse effects of climate chanie to the minimum.
