摘要
基于2019年新疆维吾尔自治区水土流失动态监测成果,以阿图什市为例,将计算得到的2019年水力、风力侵蚀面积及强度与2018年相应数据进行对比,分析植被覆盖和土地利用因子变化对水土流失动态变化的影响。结果表明:阿图什市植被覆盖因子变化影响着水土流失的整体变化,对水力侵蚀的影响较风力侵蚀更为明显;土地利用因子的变化影响着水土流失状况的局部变化,对水力、风力侵蚀的影响程度依具体的土地利用变化而定。据此,对区域水土流失相关目标责任考核提出了建议。
Taking Atushi City as an example,the paper compared the areas and intensities of hydraulic erosion and wind erosion in 2019 obtained by calculation with the corresponding data of 2018 based on the dynamic monitoring results of soil and water loss of Xinjiang in 2019 and analyzed the influence of factors change of vegetation cover and land use to the dynamic change of soil and water loss. The outcomes show that a)the change of vegetation cover factor affects the whole change of soil and water loss and the influence to the water erosion is more obvious than wind erosion and;b) the change of land use factors affects the local change of soil erosion and the degree of impact on hydraulic and wind erosion depends on the specific land use change. Based on this,some suggestions are put forward for the assessment of regional soil and water loss target responsibility.
