【摘要】：综合考虑生态经济平衡的3个方面(数量、结构和功能),基于能值理论和能值分析法构建生态经济数量平衡指数(Q)、结构平衡指数(S)、功能协调指数(F)及生态经济平衡综合指数(C),对岷江上游五县的生态经济平衡现状展开分析。结果表明:生态经济数量平衡状况以汶川、茂县和理县较好,黑水和松潘较差,这与各县的经济发展水平、土壤侵蚀强度及水电开发规模紧密相关;结构平衡状态以松潘最好,汶川次之,茂县、理县和黑水较差,这与水电开发及土壤流失等因素密不可分;功能协调状态亦以松潘最好,汶川次之,茂县、理县和黑水较差,这归因于各县的产业结构及对外开放程度不同;就生态经济平衡综合水平而言,汶川最好,松潘次之,其他三县较差。鉴于此,岷江上游各县应加强土壤流失防治、控制水电开发规模、调整产业结构并加强对外交流,从而提高系统生态经济平衡水平,推动区域可持续发展。
[Abstract]:Take into account the three aspects of eco-economic balance (quantity, quantity, Structure and function), based on emergy theory and emergy analysis method, the ecological economy quantity balance index (Q), structure balance index (S), function coordination index (F) and the ecological economy balance comprehensive index (C), are constructed to the ecological economy level of the five counties in the upper reaches of Minjiang River. The present situation of balance is analyzed. The results showed that the quantitative balance of ecological economy was better in Wenchuan, Maoxian and Lixian, but poor in Heishui and Songpan, which was closely related to the level of economic development, soil erosion intensity and the scale of hydropower development in each county, and the structural balance was the best in Songpan. Wenchuan was second, Maoxian, Lixian and Blackwater were poor, which was inextricably linked to hydropower development and soil erosion. The best coordination of functions was Songpan, followed by Wenchuan, Maoxian, Lixian, and Blackwater. This is attributed to the different industrial structure and the degree of opening to the outside world in each county. In terms of the comprehensive level of ecological economic balance, Wenchuan is the best, Songpan is the second, and the other three counties are poor. In view of this, the counties in the upper reaches of Minjiang River should strengthen the prevention and control of soil loss, control the scale of hydropower development, adjust the industrial structure and strengthen the external communication, so as to improve the balance level of the ecological economy of the system and promote the regional sustainable development.
