Exploitation and utilization of resovrces in hotan river basin and sustainable development

Located in the middle part of Hotan region,Hotan River basin is one of the important political,economic and cultural areas in Hotan region,Southern Xinjiang.However,it has the inconvenient communications,extremely fragile ecological environment ,concentrated population with a low living standard,and is in shortage of water resources.In crder to lift out of poverty and backwardness as soon as possible,the urgent matter is to rationally exploit and utiiixe the water and land resources and to protect the ecloogical environment.In this paper,the water and land resources and some existing problems in Hotan River basin are analyzed.Based on the study on the relationship between population growth,economic development,natural resources and environment in the basin,the exploitation and utilization of water and land resources as well as the ceonomic development in the future are simulated by using a developed systematical dynamic model.Finally.some suggestions are put forward for sustainable development,which are mainly to manage and distribute the water resources of the river basin unifidely,hasten the construction of water saving projects and develop water-saving irrigation,reclaim wasteland moderately,control population growth strctly,protect the green corridor and prevent the desert moving southward.
