摘要:
本研究以高淳慢城地区为研究对象,采用地理信息系统(GIS)和中国土壤流失方程(CSLE)结合的方法,研究了区域土壤侵蚀的时间和空间变化。结果表明,随着慢城区域开发过程,区域土壤侵蚀模数呈现先增加后下降的变化趋势。慢城地区2007年土壤侵蚀模数明显小于2014年和2015年,2015年土壤侵蚀模数较2014年小幅下降。慢城地区以微度侵蚀和轻度侵蚀为主,土壤侵蚀模数较大值主要分布在中南部、东北部低山丘陵区和西部龙墩河水库附近。4种土地利用中,不同年份平均土壤侵蚀模数均为旱地>林地>草地>水田。高淳慢城区域水土保持工作重点为加强对旱地的治理、缓坡修建水平梯田、陡坡退耕还林还草,慢城地区中南部、东北部低山丘陵区和龙墩河水库地区为区域水土流失治理的重点区域。研究成果对于区域水土流失时空变化精确评价与水土流失科学治理具有重要意义。
Abstract:
Taking the Gaochun slow city area as a research object, the temporal and spatial changes of regional soil erosion were studied by using the combination of Geographic Information System (GIS) and China Soil Loss Equation (CSLE).The results showed that the regional soil erosion modulus increased firstly and then decreased with the regional development process of the slow city.The soil erosion modulus in 2007 was significantly lower than that in 2014 and 2015.In 2015, soil erosion modulus decreased slightly compared with 2014.The erosion types in Gaochun slow city was dominated by micro-erosion and mild erosion.The main distribution of soil erosion modulus was mainly distributed in the low-mountain hilly area in central south and the northeast, and the Longdun River Reservoir in the west.In the 4 types of land use, the average soil erosion modulus in different years was dry land > woodland > grassland > paddy field.The focus of regional soil and water conservation work in Gaochun slow city was to strengthen the management of dry land, to build horizontal terraces on gentle slopes, to return farmland to forests on steep slopes.Therefore, the low-mountain hilly area in central south and the northeast, and the Longdun River Reservoir in the west should be the key areas of regional soil erosion control.The research results were of great significance for the accurate assessment of temporal and spatial variation and scientific management of soil erosion.
