The eco-economic system can be divided into socioeconomic and ecological sub-systems and their relationship can reveal the interaction state between the two sub-systems and help the local government to establish a coordinated development mode. An index system was constructed to assess the development of the two sub-systems before the evaluation of the degree of coupling and coordination. The principal component regression analysis was adopted to quantitatively assess the influences of natural, economic and social factors on the degree of coupling and coordination of the eco-economic system. Results showed that, from 1983 to 2014, the development trends of both sub-systems were increasing with the ecological sub-system having more fluctuations. The degree of coupling and coordination of the eco-economic system in the study area increased gradually from 1983 to 2014, but experienced five different development stages from the verge of disorder to favorable coordination. The development of the local social and economic conditions was the most important factor influencing the degree of coupling and coordination. The second most important factor was the financial support from the local government. In addition, the environment protection policies also played undeniable roles. Due to the diversity of the influence factors, the government should take comprehensive measures to promote the sustainable development of the eco-economic system.展开更多

The results show that the rate of contribution of water conservation,soil conservation,carbon-fixation and oxygen-production functions to regional service value is high ( 37. 05%,36. 68% and 23. 15%,respectively) ; the rate of contribution of production of organic matter and purification of atmospheric environment functions to regional service value is low ( 2. 80% and 0. 32%,respectively) . The ranking of landscape in terms of service value per unit area is as follows: forestland ( 23.353 9 million yuan) > shrub land ( 10.630 1 million yuan) > grassland ( 5.036 7 million yuan) > dry land ( 3.381 2 million yuan) > farmland ( 2.508 8 million yuan) . The ranking of demonstration areas in terms of service value per unit area is as follows: Yachi Demonstration Area ( 12.44 million yuan) > Hongfenghu Demonstration Area ( 5. 91 million yuan) > Huajiang Demonstration Area ( 4. 4 million yuan) . It is negatively correlated with rocky desertification incidence within the region. The results also indicate that in the process of restoring and reconstructing the ecological environment in rocky desertification areas,increasing the area of forest vegetation,promoting the conversion of dry land and farmland into forestland, shrub land and grassland,will contribute to enhancement in ecological service value.展开更多
