| 摘 要： | 土壤侵蚀受多种因素的影响和制约.根据美国土壤侵蚀通用方程以及济南市独特的自然地理特征,确定了济南市土壤侵蚀敏感性主要评价因子,包括降水、地形起伏、土壤质地和植被.在GIS系统支持下,提取单因子数据并得到单因子土壤侵蚀敏感性,进而完成土壤侵蚀敏感性综合评价.运用GIS空间分析功能,得到不同敏感性程度的面积与空间分布规律,从而为政府制定水土保持政策提供科学依据.

| Abstract: | Soil erosion is limited by various factors.Guided by the Universal Soil Loss Equation and the unique geographic features of Ji'nan City,primary evaluation factors for the sensitivity of soil erosion in Ji'nan City are determined,including precipitation,terrain undulation,soil quality,and vegetation.Every single factor is extracted and its sensitivity of soil erosion is obtained with the support of GIS technology.The comprehensive evaluation is then completed based on the work.By using the spatial analysis of GIS,it is easy to find the area and spatial distribution of different sensitivity grades.The study provides a scientific basis for governments to make policies of soil and water conservation. |
