地统计方法在土石山区土壤侵蚀空间变异性研究的应用

土壤侵蚀是一种复杂的空间随机分布现象,其影响因素多,对其做出合理有效的定量分析难度较大。近年来,GIS技术及地统计学的迅猛发展为我们攻克土壤侵蚀空间变异这一难题提供了可能。以西南土石山区水土保持项目为依托,尝试地统计方法在土壤侵蚀空间变异性研究的应用,建立了地统计学方法在土壤侵蚀空间变异性研究中应用的基本技术流程。以便其在小流域土壤侵蚀的定量评价、规划与治理以及动态监测等方面提供理论研究和实际应用。

Advance in Spatial Variability of Soil Erosion in Mountainous Area by Using Geostatistics

Soil erosion is one kind of complex spatial random distribution phenomenon with many influcing factors,it is difficult to make a reasonable effective quantitative analysis.In recent years,GIS and Geostatistics swift and violent development give us the possibility to solve the difficult problem of the spatial variability in soil erosion's research.Basing on the conservation of water and soil project in soil and rock mountainous area in the Southwest of China,the research of soil erosion's spatial variability is made applying the method of Geostatistics,and the basic program is set up in order to provide the fundamental research and the practical application for the soil erosion quantitative evaluation,plan and management as well as dynamic monitoring.
