【摘要】：綜合考慮生態(tài)經(jīng)濟平衡的3個方面(數(shù)量、結(jié)構和功能),基于能值理論和能值分析法構建生態(tài)經(jīng)濟數(shù)量平衡指數(shù)(Q)、結(jié)構平衡指數(shù)(S)、功能協(xié)調(diào)指數(shù)(F)及生態(tài)經(jīng)濟平衡綜合指數(shù)(C),對岷江上游五縣的生態(tài)經(jīng)濟平衡現(xiàn)狀展開分析。結(jié)果表明:生態(tài)經(jīng)濟數(shù)量平衡狀況以汶川、茂縣和理縣較好,黑水和松潘較差,這與各縣的經(jīng)濟發(fā)展水平、土壤侵蝕強度及水電開發(fā)規(guī)模緊密相關;結(jié)構平衡狀態(tài)以松潘最好,汶川次之,茂縣、理縣和黑水較差,這與水電開發(fā)及土壤流失等因素密不可分;功能協(xié)調(diào)狀態(tài)亦以松潘最好,汶川次之,茂縣、理縣和黑水較差,這歸因于各縣的產(chǎn)業(yè)結(jié)構及對外開放程度不同;就生態(tài)經(jīng)濟平衡綜合水平而言,汶川最好,松潘次之,其他三縣較差。鑒于此,岷江上游各縣應加強土壤流失防治、控制水電開發(fā)規(guī)模、調(diào)整產(chǎn)業(yè)結(jié)構并加強對外交流,從而提高系統(tǒng)生態(tài)經(jīng)濟平衡水平,推動區(qū)域可持續(xù)發(fā)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.
