江西东江源区森林涵养水源价值评估与保护对策

Evaluation and Protection Strategies of Conserving Water Resources by Forests in Dongjiangyuan Areas, Jiangxi

东江源区是以森林涵养水源为主导功能的国家生态功能保护区建设试点区,涵盖江西省南部的寻乌、安远、定南三县。东江是珠江三角洲和香港地区的主要饮水水源。江西东江源区流域面积3 524 km2,虽只占东江全流域面积的13%,但向珠江三角洲和香港地区的供水量约占总供水量的近40%,加强源区保护和建设,保持其优良的水质和充足的水量,直接关系到香港和珠江三角洲工农业生产和居民的生活,对香港的稳定、繁荣和珠江三角洲的可持续发展,具有特别重要的意义。目前东江源区,人口压力和强烈的经济发展需求使保护区面临严峻挑战,创新东江源区森林涵养水源保护机制,协调生态保护与经济社会发展的关系已刻不容缓。

Dongjiangyuan areas,covering Xunwu,Anyuan and Dingnan three counties located at the south of Jiangxi Province,were the pilot area of constructing national ecological function reserve which mainly aimed at conserving water resources by forests.The Dong River was the main drinking water source for the Pearl River Delta and HongKong city.The drainage area in Jiangxi was 3 524 km2,although only occupied 13% of the whole drainage area,but the water supply for the Pearl River Delta and HongKong was about 40% of the total water supply.Strengthening protection and construction of this area,keeping excellent water quality and ample water supply have direct relations with the industrial and agricultural production and the living in Pearl River Delta and HongKong.It has significant meaning for the stability and prosperity of HongKong and the sustainable development ability of the Pearl River Delta.At present,pressure of population increasing and strong requirement of economy development gave an urgent challenge to Dongjiangyuan areas.Innovating protection mechanisms of conserving water resources by forests in Dongjiangyuan areas and coordinating the relations between ecological environment protection and economic social development have no time to delay.
