Land-Use and Land-Cover Change and Its Climatic Consequences — A Case Study of Xishuangbanna, China

Abstract

With the rapid development of economy, human activities have generated changes to some components of the climate system. LULCC have resulted in one important consequence for climate change. Xishuangbanna’s rubber plantation area was more than 271 kha accounting for 27.1% of total China’s rubber plantation, comparing its land area 2% of total china’s land area, this rate was very high. This expansion of rubber plantation has causing large loss of primary forest, and has steadily increased and affected local climate. The annual mean temperature, in the past 50 years, Xishuangbanna annual average temperature was overall upward trend, the growth quantity of 0.252 centigrade for per decade, the annual increase rate of 0.13%; annual precipitation, relative humidity and foggy weather days were decreasing fast. In this paper, it will focus on exploring the climatic consequences of LULCC. Then using linear regression equation and climate tendency rate to find their changing trends, according the analysis and predict of variation tendency to give the corresponding suggestion that not to decrease primary forest from current conditions in order to conservation, reforestation and afforestation, furthermore to restore forest to be a healthy condition.
