绿洲城市化与生态环境互动作用 关系研究进展

绿洲城市化与生态环境互动作用关系研究经历了萌芽、发展和多元化研究三个阶段。近年 来, 国内外学者继承了绿洲城市化与自然环境变迁关系的历史学分析, 多角度探讨了绿洲古城国 产生、繁荣和衰落过程中的自然因素和人为因素作用; 十分重视水资源约束下的流域绿洲城市化 研究, 基本确立水资源约束和上、中、下游协调发展为研究切入点; 非常注重绿洲城市化与生态环 境相互作用机理探究, 从中、长时间尺度分析了绿洲城市化与生态环境的耦合关系及其阶段性特 征; 广泛采用空间技术、复杂系统分析和数学分析等定量方法评估了城市化与生态环境的响应过 程; 普遍关注绿洲城市化对生态环境正负效应的辨析; 逐步加强对可持续绿洲城市化模式和对策 的探索, 并总结了绿洲城市化与生态环境协调发展的经验与教训。从研究趋势来看, 今后在研究 的可控性与对实践的指导性、多学科交叉研究和系统动态性研究等方面将得到加强。

Resear ch Progr ess on Inter action between Urbanization and Eco- environment in Oasis Area

Based on the retrospection of researches on interaction between urbanization and eco-environment in oasis area,this paper reviewed systematically the relative research progress and prospected the main research directions in the future.Studies showed that the domestic and international scholars succeeded to the history analysis of urbanization and eco-environment relation in oasis areas,paid close attention to the research of oasis urbanization in drainage areas under the condition of water deficiency,and thought much of the research of oasis urbanization and eco-environment interaction mechanism.They generally adopted space analysis technology,complex systematic analysis and mathematics models to appraise the response course of urbanization and eco-environment respectively,paid more attention to differentiating the positive and negative environment effects of urbanization in oasis areas,and strengthened the research on sustainable urbanization patterns in oasis areas.There are still a lot of weak points for recent researches.In the future,the controllability,the close integration with practice,and the cross-disciplinary and systematic dynamic simulation will be the main research trends.
