罗布泊气候环境时空变化特征及未来演变分析
Analysis of spatiotemporal changes and future evolution of the climate environment in Lop Nur
摘要
Abstract
Based on China's regional surface meteorological elements driven dataset(CMFD)and Grace gravity satellite data,the spatio-temporal variations of temperature,precipitation,evapotranspiration and groundwater level in Lop Nur region were analyzed.The results showed that the average annual temperature in Lop Nur area was 12.9℃.The annual average precipitation was 6.2mm,and the annual average precipitation was 6.2mm.The potential evapotranspiration is an order of magnitude greater than local precipitation.According to the GRACE satellite calculation results,the groundwater level showed a decreasing trend.Hurst index indicated that the future temperature,precipitation and evapotranspiration in Lop Nur will decrease,increase and slowly decrease,respectively.In the future climate change,the changes of climate environment and groundwater level would not affect human activities such as railway construction in the lake basin.关键词
