南方红壤丘陵区县级水土保持区划研究——以零陵区为例

RESEARCH ON THE COUNTY-LEVEL SOIL AND WATER CONSERVATION REGIONALIZATION IN THE SOUTHERN RED SOIL HILLY REGION

选取零陵区为南方红壤丘陵区县级水土保持区划研究对象,确定水土保持区划体系以人居环境维护和保土减蚀为重点,综合考虑水源涵养、水质维护、生态维护、防灾减灾以及农田防护等方面的需要,划分出5个不同类型的水土保持功能区:东南部山地水源涵养生态维护区、南部低山丘岗防灾减灾保土区、北部丘岗人居环境维护保土区、中部盆谷农田防护保土区、西南部山丘水质维护生态维护区。

Lingling District was selected as the object of the county-level soil and water conservation regionalization research for the red soil hilly area in southern China. Soil and water conservation regionalization system focuses on the maintenance of living environment and soil. Based on the needs of water conservation, water quality maintenance, ecological environment maintenance, disaster prevention and mitigation and farmland protection, Lingling district was divided into five different soil and water conservation function regions： water conservation function region in the southeastern mountainous area, disaster prevention and mitigation region in the southern low hilly area, living environment maintenance and soil conservation region in the northern hilly area, soil and farmland protection region in the central basin valley area, and water quality and ecological maintenance region in the southwestern hilly area.
