喀斯特山区土地利用变化与土壤侵蚀耦合关系研究——以毕节试验区为例
- Title:
- Relationship Between Land Use and Soil Erosion in Karst Area-A Case Study of Bijie Experimental Area
- Keywords:
- land use/cover change; soil erosion; overlay analysis; transfer matrix; Bijie experimental area

- 摘要:
- 利用RS与GIS技术，提取地类、坡度和植被等3个因子的数据信息，模拟1990-2010年毕节试验区的土地利用过程和土壤侵蚀变化过程，并运用叠置分析和转移矩阵分析的方法，分析了土地利用变化过程中土壤侵蚀的响应特征，揭示土地利用变化及土壤侵蚀变化的关系。结果表明：毕节试验区土地以林地、耕地、草地为主，耕地面积不断减少，林地和建设用地面积不断增加；土壤侵蚀以轻度、中度侵蚀为主，整体呈现改善的趋势，尤其是退耕还林后，土壤侵蚀的面积与强度均不断降低；土地利用变化与土壤侵蚀具有密切的联系，耕地是土壤侵蚀发生的主要土地类型，耕地的减少与土壤侵蚀呈正相关关系，林地面积变化与土壤侵蚀具有较好的相关性，但在退耕还林的初期，土壤侵蚀的强度略有增加，草地增加与土壤侵蚀负相关，增加草地有利于土壤抗侵蚀能力的增强。研究喀斯特山区土地利用与土壤侵蚀的耦合关系，有利于有限的土地资源的合理配置和喀斯特地区的生态保护，为区域土地规划及水土保持等宏观决策部门提供理论支撑。
- Abstract:
- The process of land use/cover change and soil erosion change in Bijie experimental area from 1990 to 2010 was simulated by analyzing the data of land use type, gradient and vegetation index based on RS and GIS. Then, through overlay analysis and transfer matrix analysis, the response characteristic of soil erosion during changing process of land utilization was analyzed. The relationship between land use change and soil erosion change was revealed finally. The results showed that:(1) the areas of forestland, cultivated land and grassland in Bijie experimental area were the largest, the area of cultivated land was decreasing gradually, the areas of forestland and building land were increasing gradually; (2) the main types of soil erosion were mild and moderate erosion, the degree of soil erosion was controlled to a better level over the past twenty years, especially after the implementation of Grain for Green Project; (3) the land use change process was closely associated with soil erosion; cultivated land was main land type for the occurrence of soil erosion, the decreased area of cultivated land was positively associated with soil erosion area; the change in area of forestland was interrelated to the soil erosion, while at the beginning of the Grain for Green Project, the intensity of soil erosion slightly increased; the increased area of grassland was negatively correlated to the soil erosion area; increase in grassland area is favorable for strengthening anti-erosion ability of the soil. The results of this research are helpful for rational configuration of land resources and ecological protection in karst area and also provide the decision-making support for organization such as land use planning bureau or water resources bureau.
