针对红寺堡新绿洲存在着风沙灾害频繁,种植业结构单一,水资源供需矛盾突出,土壤肥力低下以及移民经济基础薄弱和科技文化素质较低等制约因素。从可持续发展的生存支持子系统、发展支持子系统、环境支持子系统、社会支持子系统及智力支持子系统等5个子系统的相关方面分析了该区可持续发展所面临的问题,提出了建立节水型农业生产体系,实现水资源增值;建设完整的防护林网体系;建立混合型及少耕、免耕的保护性耕作制度;快速培肥土壤,建设高产农田系统以及调整产业结构和控制人口数量,提高人口素质等对策。

Some limit factors on Hongsipu New Oasis are frequency sand blown by wind disaster,singularity planting industry structure,extrot rusible contradiction with supply and demand of water resource,low soil ferti-lity,weak emigrant economic foundation and poor knowledge with science and technology.The problems with the sustainable development on the area are analyzed from the sustainable development of five related aspects,which are the survival sustained subsystem of sustainable development,developmental sustained subsystem,environmental sustained subsystem,social sustained subsystem and intellective sustained subsystem.It is suggested that to set up the water-saving type agricultural system,and realize water resource multiaplication;to build integrated shelter belt system and mix conservative tillage system of zero tillage and minimum tillage,and to cultivated soil quickly in order to set up high yield agricultural system.Countermeasures are brought forward,which are adjustability industry structure,control population number and improvement population quality.
