摘要
水在干旱区维护生态和发展经济中起决定性作用,而水资源的形成、转化和消耗,主要取决于大地貌类型。本文以大地貌类型为单元,将玛纳斯河流域划分为3个生态经济功能区;即南部天山草原森林牧林矿产区,对应为径流形成和水源涵养区;中部玛纳斯河平原农业和城镇绿洲区,对应为径流消耗和转化区;北部古尔班通古特沙漠生态保育沙产业区,对应为少流和无流区。在3个一级区划内,再根据中地貌条件、生态系统类型、产业结构及发展经济和保护生态环境的措施划分二级区,共分为9个。分别论述了各区的生态环境与社会经济特征,有针对性的提出各区生态与经济协调发展的对策,为分区治理提供了科学依据。并提出只有把玛纳斯河流域作为一个完整的生态经济系统,实行以水资源合理利用为核心,以山区的综合治理为基础,以发展绿洲经济为支撑,以防治荒漠化的扩大为保障,才能使其良性互动,实现和谐和持续发展。
For the decisive role of water in eco-protection and economy development in arid regions and the dependence of its formation, transformation and consumption on topography, this paper zones Manas River Basin into three major regions according to different topographies ： （ 1 ） south region, including grassland, forest, grazing and mining areas of north slope of Tianshan Mts. , where runoff is formatted and water resources conserved ; （2） middleregion, including plain and township near Manas River, where runoff is consumed and transformed; （3） north region,including eco-protected area of south edge of Gurbantongut Desert, where flow is few. Then the three regionsare divided into nine sub-regions based on ecosystem types, industrial structures, economy development level and eco-protection. Characteristics of eco-environment and economy both of the integral Manasi River Basin and sub-re-gions are studied respectively and corresponding measures are put forward to use water rationally, manage mountains comprehensively, develop economy rapidly, and prevent desertification strictly, and this providing scientifc basis forregionalization management and eco-economic harmonious development.
