新疆和田绿洲适宜规模的研究

在水热平衡基础上,同时考虑生态与环境的要求,建立了适宜绿洲规模以及适宜灌溉规模的数学模型,计算出和田绿洲的适宜面积为6080~7690km2,现状条件下和田绿洲规模已达8420 km2,略超出适宜规模;同时计算出和田绿洲的适宜灌溉面积为14.67~18.66万hm2。目前的灌溉面积以及规划的灌溉面积尚在适宜范围之内,但必须节水,否则,水资源紧缺将会危及绿洲社会经济的可持续发展。

Study on the Suitable Scale for Hotan Oasis,Xinjiang

In view of requirement of ecology and environment,based on the water and heat balance,a mathematical model was set up for the suitable oasis scale.The suitable oasis area is 6,080-7,690km2 for Hotan Oasis,which is lower than the existed oasis area(8,420km2).The suitable irrigation area in the Hotan oasis is 14.7×104-18.7×104hm2.The existed irrigation area is 15.5×104hm2 and the irrigation area planned in future is 16.3×104,still within the suitable range.But water saving have to be carried out otherwise water shortage would affect the sustainable development of society and economy in Hotan.
