Analysis on Spatial Geographical Region of Soil and Water Loss Caused by Urbanization Construction
According to the rate of economic development and the characteristics of geographic location and to pographic structure of Hangzhou city
the spatial distribution characteristics of soil and water loss caused by urbanization construction are analyzed.The conclusions are as follows:(1) Taking city area as a center
the influence circle zones of urbanization construction expand toward west at fan-shaped.The width of influence circle zone is narrow;(2) The terrace topographic structure and two highways divide fan-shaped influence circle zones into checked net circle zones;(3) The transition is very sudden from the good results zone of protecting environment to the concentrated zone of construction;(4) The providing zone of building materials is the main occurring zone of soil and water loss;(5) The vegetable plots of various utility ways are main potential source of soil and water loss because these vegetable plots move toward slope land step by step.
