江西赣江沙害的流域生态学以及治理的初步研究

江西赣江是我国南方的重要河流,流域面积约占省域的一半.目前,其干流、部分支流和部分流域的沙害已极为严重,航运功能已基本丧失.本文对赣江的沙害进行了流域生态学的研究,以探索其流域中的沙源,部分流域的严重生态破坏和粗沙流出的原因,粗沙的流出量,以及沙害对生态环境和经济发展的影响.同时,也对沙害的相对完全治理进行了小流域的实验和示范,并提出了相关的推广建议.

Study on Sandy Calamity and Its Controls in the Ganjiang River,Jiangxi Province

The Ganjiang.Is a important river in Southern China.Its drainage area covers nearly half of Jiangxi Province.At present,the sandy calamity is very serious in the Ganjiang and a part of tributary,which have lost the shipping function basically.This research work has investigated the source of sand,the cause of erosion,the volumes of coarse sand,the influence on ecologic environment and economic development.This research work has set up also the experimental and demonstrative small watersheds at relative complete controls.
