| 摘 要： | 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. |

Evaluation on the coordinated development ability of eco-economic system in Hexi Corridor oases |
|
| Abstract: | Coordinated development of ecology and economy is the major avenue to realize sustainable development-of Hexi Corridor oases, Gansu Province, China, which can do well to its fragile ecological environment and high binding character of the economic development. The paper constructs an index system of coo-economic system of Hexi Corridor oases, which is based on a thorough analysis of the status of the ecological environment and the eco-nomic development in Hexi Corridor, and then the actuality of the coordinated development degrees of eeo-economic system and the coordinated degrees of its subsystem were simulated and analyzed by using entropy method and the coordinated degree model. The results are as follows: both the ecological benefits and the economic benefits show a low level in 5 oases of Hexi Corridor, there is not a favorable coordinated development region. The coordinated de-velopment ability of each oasis demonstrates the following precedence order of Jiayuguan > Jinchang > Zhangye > Ji-uquan > Wuwei. Jiayuguan belongs to the region with the grudgingly coordinated development, and its coo-environ-mental regeneration is lagged. Jinchang, Zhangye, Jiuquan and Wuwei belong to the regions with the imbalance and recession development. Among them, the ecological and economic regeneration of Jinchang and Jiuquan are synchronous, the eeo-environmental regeneration of Zhangye and Wuwei are lagged. At last, the development di-rection of each oasis and some countermeasures and suggestions are proposed. |
