| 中文摘要: |
| 以中国南方典型的红壤和紫色土丘陵区——衡阳盆地为例,分析论述了衡阳盆地地表水资源脆弱性主要表现在:降水资源时空分布不均匀;不利于水土保持的地表物质组成和植被覆盖;耗水量大的农业种植结构以及调蓄水功能弱的农田水利工程体系等方面。提出了农业水资源管理的主要对策:一是强化地表雨水的资源化过程;二是加强农田水利设施的建设以及建立节水型的农林复合生态系统。 |
| 英文摘要: |
| The primary representations of the vulnerabilities of water resource in Hengyang basin where is a typical hilly region with red and purple soils in south China are analyzed： the precipitation resource varies greatly in spatial and temporal distribution；the soils and rock property are not in favor of water and soil conserving；the structure of crops needs a high water consumption；and the farm irrigation works are timeworn and frangible．Some management countermeasures are proposed： constructing new water conservancy projects and improving old irrigation works，intensifying the utilization process of surface rainfall sources，and establishing water-saving cropping-forestry-herbage compound ecological system． |
