深圳市位于南亚热带南部,地势为东高西低,东部山地,山高坡陡,构成岩石以火山岩和石英岩为主,西部滨海平原,组成物质以冲积洪积物为主,中部为低丘台地,以花岗岩和砂页岩为主。深圳水土流失区主要分布在中部的花岗岩低丘台地上。研究水土流失问题,对于山地合理利用、环境保护及当地农业生产,有现实意义。本文以1982—1983年在深圳土地资源调查中所获得的资料,通过对水土流失现状的剖析,探讨其引起侵蚀的原因,并提出整治意见。
Shenzhen is located in the southern part of the southern subtropics. Its terrain is high in the east and low in the west. The eastern part of the mountain is steep and the mountain is steep. The volcanic rock and quartzite are the main rocks in the city. The western coastal plains consist of alluvial sediments and alluvial sediments, , Mainly to granite and sand shale. Soil erosion in Shenzhen is mainly distributed in the central granite plateau. Studying the problem of soil and water loss is of practical significance for the rational utilization of mountainous areas, environmental protection and local agricultural production. Based on the data obtained from the survey of land resources in Shenzhen from 1982 to 1983, the paper analyzes the current situation of soil and water loss, discusses the causes of erosion and puts forward suggestions for remediation.
