河西走廊:绿洲支撑着城市化!——与仲伟志先生商榷 总被引:18,自引:5,他引:13
针对仲伟志先生在《经济观察报》(2002年10月14日)撰写的《河西走廊:城市化覆盖绿洲?》一文的若干观点,提出了自己近年来研究河西走廊得出的基本看法。作者认为,在河西走廊,有绿洲就有城市,有城市就有城市化;城市化不会覆盖绿洲,城市化会推动绿洲更加走向繁荣;水源绝不是城市化的最大瓶颈,城市化更不会制造沙漠;在保护绿洲生态环境的同时,加快走廊城市化发展进程,这是河西走廊生态环境改善和人民生活水平提高的有效途径。绿洲支撑着城市化,合力共筑着河西走廊作为中国西部生态经济走廊的开发与发展。 相似文献

河西走廊绿洲生态经济系统协调发展能力评价 总被引:7,自引:4,他引:3
河西走廊生态环境脆弱,经济发展约束性强,生态与经济协调发展是实现绿洲可持续发展的重要途径.在对河西走廊生态环境与经济发展现状深入分析的基础上,构建了绿洲生态经济系统指标体系,采用熵权法,运用协调发展度模型,对5个绿洲生态经济系统及其子系统的协调发展度及协调度进行了定量分析.结果表明:各绿洲生态效益、经济效益水平均很低,尚不存在良好协调发展区域;绿洲协调发展能力呈现为嘉峪关>金昌>张掖>酒泉>武威的顺序,嘉峪关属于勉强协调发展类生态滞后型区域;金昌、张掖、酒泉、武威同属于濒临失调衰退阶段,其中金昌、酒泉属于生态经济同步型区域,张掖、武威属于经济滞后型区域,据此提出各绿洲的发展方向与对策建议. 相似文献

中国内陆河流域绿洲发育度的综合评价 总被引:8,自引:0,他引:8
人工绿洲是干旱区人类活动主要场所,绿洲管理和生态建设体现了人类活动的积极作用;而不适当的土地开发与经济活动又形成了对绿洲生存与可持续发展的过度压力与生态负荷。科学准确地对绿洲状态进行综合评价,已成了人们正确认识绿洲并对其进行生态建设和环境保护的重要前提。针对目前我国绿洲综合评价研究的指标单一、应用区域受限等缺陷和不足,提出了可普遍用于内陆河流域绿洲评价的指标体系--基于因子分析法的“绿洲发育度”,并以河西走廊的15个绿洲为研究对象进行了案例分析。结果表明:依据发育度综合评价值可将河西走廊绿洲划分为工业绿洲、较高开发程度的农业绿洲、中度开发的农业绿洲和衰退或较低开发程度的农业绿洲4个等级,与当地实际情况完全符合;同时,还可通过因子水平上的发育度指标对各个绿洲的优势和劣势进行准确的定量表达,为绿洲管理者和政策制定者提供简明、准确的科学依据。 相似文献

河西走廊绿洲面积动态及其驱动因素 总被引:4,自引:3,他引:1
绿洲是干旱区脆弱生态体系中由人类活动与自然因素综合作用形成的、能够为人类生存与发展提供物源基础和生态服务功能的重要地理单元,其动态变化能够反映区域内生态、经济以及社会的演替方向。以第四次和第五次全国荒漠化和沙化监测数据为基础,结合同期气象与人类活动数据,应用转移矩阵与灰色关联度分析法,分析了河西走廊绿洲土地利用类型的转移规律和环境因素对绿洲动态变化的影响程度。结果表明:(1)研究时段内,河西走廊绿洲内部土地利用类型动态转移明显,相互间转化剧烈的地类包括耕地、居民工矿交通用地、有林地、灌木林地和草地;(2)河西走廊5个地级行政区绿洲面积均呈增加趋势,增加幅度最大的为嘉峪关市(51.97%),最小的为武威市(3.68%);(3)驱动河西走廊5个地级行政区绿洲面积动态变化的主导因子与农耕产业关系密切,预示河西走廊水资源利用与农业生产效率仍需提高。 相似文献

论河西绿洲灌区节水型集约持续农业之发展 总被引:1,自引:0,他引:1
通过分析河西绿洲农业区光能、土地、水、矿藏资源优势,对该区的粮食生产力、种植业结构调整、畜牧业、农畜产品加工业生产力进行了估算,指出在计划经济向市场经济转轨,粗放经营向集约经营转变的过程中面临的突出问题。河西绿洲农业可持续发展的出路在于建设高标准永久性农田、开发节水农业技术体系、建设节粮型商品化牧业基地、兴工致富、兴办农业高新技术示范园区,促进农业由劳动集约向资本和技术集约转变。 相似文献

金塔鸳鸯池灌区地下水动态演变及其对环境影响 总被引:1,自引:1,他引:0
金塔盆地属甘肃省河西走廊沙漠化强烈发展地区,倘若水资源利用不当更加加剧沙漠化过程。因此,合理开发利用地下水资源是本区农业生产持续发展和环境保护的关键问题之一。本文作者建议以盆地为整治单元,全面规划、定向控制,坚特以开源与节流结合,"蓄、引、灌、排、补"并举,综合整治山、水、田、林、路。统一管理地表水与地下水开发利用,并建立绿洲防护体系,以建立高效稳定的农业生态绿洲。 相似文献

滑坡危险度区划研究述评 总被引:12,自引:3,他引:12
滑坡危险度区划是滑坡研究发展到一定深度所提出的新课题。到目前为止,我国既无统一的滑坡危险度评价理论体系,也无统一的滑坡危险度区划制图方法。因此,该项工作异常薄弱,这是造成预防不及时,措施不力,从而导致广泛、严重滑坡灾害的原因之一。滑坡危险度区划的主要目的是:①建立标准化评价体系;②滑坡信息库;③评价区域滑坡的危险性;④提供标准化危险度区划图件;⑤减灾防灾的决策依据。文章对此问题的研究动态评述基础上。提出了危险度区划的内涵和研究目标。 相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world's largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing. 相似文献
