摘要
基于GIS技术深入分析USLE模型中各因子在黑龙江省典型黑土区的适用情况,结合区域特点对模型因子进行选择和修正,研究分析2005、2010、2015和2020年的土壤侵蚀模数和侵蚀强度的时空变化。结果表明:研究区主要侵蚀类型为微侵蚀,平均占总侵蚀面积82.52%;轻侵蚀和中侵蚀有向微侵蚀转移的良好表现,其他强度侵蚀零散分布,共占比仅为0.076%;整体侵蚀向好发展。本研究有助于为黑龙江省典型黑土区精准侵蚀防治提供决策依据。
The application of each factor in the USLE model in the typical black soil areas of Heilongjiang province was deeply analyzed based on GIS technology.The model factors are selected and revised according to the regional characteristics.The study analyzed the spatiotemporal changes of soil erosion modulus and erosion intensity in 2005,2010,2015,and 2020.The results show that:the main erosion type in the study area is micro-erosion,accounting for 82.52%of the total erosion area on average;light erosion and medium erosion have good performance of transferring to micro-erosion,and other intensity erosion is scattered,accounting for only 0.076%;the overall erosion is developing positively.This study is helpful to provide decision-making basis for precise erosion prevention and control in typical black soil areas of Heilongjiang province.
