摘要

Desertification is the world's most serious environmental problems. And there are 20% of the land is under threat of desertification. In recent decades, with the continuous increase in population, deforestation of excessive land denudation, use of resources over exploitation, urban development and other strength of human activities increases, the surface vegetation severely damaged, intensity of land desertification developed, the capital of eco-environment of greatly affected, threatens the ecological security of Beijing, Beijing against desertification has become one of the four ecological environment. Desertification and climate change caused by human activity both vegetation cover is damaged, quicksand is formed and the process of bare sand. In this paper, Beijing 1951-2009 socio-economic development of the meteorological information and statistical data analysis, summed up the temperature, precipitation, wind, evaporation and other major changes in climatic factors, and human econormc activities on the strength. In this paper, while Beijing Remote Sensing Interpretation of changes in land desertification the last 20 years, integrated analysis of climate change and human activities on the impact of desertification. The results show that desertified land in Beijing is mainly distributed on both sides of Chaobai and Yongding River, Wenyu River along the coast, Kangzhuang district, south exit region, Huairou and Miyun Dasha areas; In the by the dual impact of the game driven by climate-driven natural factors and landuse-driven human factors in Beijing in the last 20 years on the interference of desertified land, natural factors account for a dominant role. The research for the study of the causes of land desertification in Beijing and its evolution trend, for ease population-resources-environment conflicts, promote the coordinated development of capital, stable and sustainable social and economic significance.
