摘要
榆林地处毛乌素沙地与黄土高原过渡区,生态环境极度敏感。近15年来,因经济高速发展驱动的人工生产建设项目对自然环境产生极大破坏,使得沙化土地面积占比仍然很高,亟需加大治理力度。榆林土地荒漠化、沙化及沙尘暴定位监测始于2002年,至今已有19年的历史,本文从气象、土壤、植被、地下水位角度做了连续多年的详实监测。在总结出沙化监测结果与原因分析基础上,提出了防沙治沙的决策及建议,旨在为榆林科学治沙提供决策依据。
Yulin is located in the ecological transition zone between Mu Us sandy land and Loess Plateau,and the ecological environment is extremely sensitive.In the past 15 years,due to the destruction of nature caused by artificial production and construction projects driven by rapid economic development,the proportion of desertification land has been still very high,so it is urgent to strengthen governance.The location monitoring of land desertification,desertification and sandstorm in Yulin began in 2002,with a history of 19 years.This study does a detailed monitoring of many years from the aspects of meteorology,soil,vegetation and groundwater level.The monitoring results and cause analysis are summarized,and the decision-making and suggestions for sand prevention and control are put forward,in order to provide decision-making basis for scientific sand control of Yulin municipal government.
