中山市平原河网区水土流失易发区划分研究
|
摘要
[目的]开展中山市境内平原河网区水土流失易发区的划分工作,为更好地贯彻落实《水土保持法》,保护宝贵的水土资源,为政府依法行政、实施生产建设项目水土保持管理提供科学依据。[方法]通过分析区域内土壤抗蚀性弱,母岩易风化,降水多,强度大且年内分布不均,水热条件充裕等自然特点,以及人类社会经济活动较强等社会经济特点,基于GIS,RS技术开展研究。[结果]通过划分水土保持分区,明确了需界定水土流失易发区的平原河网区范围,也探明了研究区地形地貌、降雨、土壤、植被及河网区水土流失易发敏感因子,合理选取定量和定性指标,构建了水土流失易发区划分指标体系,划分出中山市平原河网区水土流失易发区。[结论]中山市平原河网区水土流失易发区主要有小榄镇、黄圃镇等9个镇区,土地面积约666.92km2,占该市土地总面积的37.39%。易发区划分成果完善了中山市水土保持规划体系,同时也可为编制地市级水土保持规划或制定规章制度提供依据。
[Objective]The soil erosion prone area in the plain river network region of Zhongshan City was dividedfor the implementation of soil and water conservation law and the protection of precious soil and water resources in order to provide the scientific basis for the government to administrator according to law and implementation of the water and soil conservation management of production construction projects.[Methods]Through the analysis of natural characteristics of the region,such as weak soil erosion resistance,easy weathering of parent rocks,heavy rainfall with uneven distribution during the year,abundant water and heat conditions,and social and economic characteristics such as strong social and economic activities of human beings,GIS & RS technology is used.[Results]By dividing soil and water conservation zones,the range of plain river network areas,where soil and water was easy to lose,was defined.The sensitive factors of soil and water loss such as landform,rainfall,soil,vegetation are determined in Zhongshan plain river network area.Also,the index system of soil erosion prone area division is constructed by selecting quantitative and qualitative indexes,and the soil-erosion-prone area in the plain river network area of Zhongshan City is divided.[Conclusion]The soil erosion prone area in the plain river network area of Zhongshan City which includes Xiaolan town,Huangpu town and other 9townships,whose land area is about 666.92km2,accounting for 37.39% of the total land zone of the city.The achievements in the division of soil erosionprone area can improve the planning system of soil and water conservation in Zhongshan City,and also can provide a scientific basis for the compilation of soil and water conservation planning at the prefectural level or for the formulation of rules and regulations.
