Division of Soil Erosion Prone Area in Plain River Network Area of Zhongshan City
[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 9 townships
whose land area is about 666.92 km2
accounting for 37.39% of the total land zone of the city. The achievements in the division of soil erosion prone 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.
