Evaluation of Value Transformation of"Two Mountains"in Guangxi Based on Emergy
In order to investigate the value conversion efficiency between"green mountains"and"silver mountains"in Guangxi,the input and output model of value conversion of"two mountains"is constructed by the energy value method,and the level of value conversion of"two mountains"and the intensity of ecological capital impairment in Guangxi from 2000 to 2020 are evaluated,and the value conversion rate of"two mountains"in the next five years is predicted by the gray prediction model.The results are as follows.(1)From 2000 to 2018,the value transformation level of Guangxi's"two mountains"showed a large adjustment process of fluctuating upward on the whole,and there was a small downward trend from 2018 to 2020.(2)During the studied period,the impair-ment intensity of Guangxi's ecological capital showed a trend of decreasing first and then increasing.The absolute driving force to promote the impairment of Guangxi's ecological capital is industrial waste emissions.(3)From 2000 to 2020,the predicted value of the value conversion rate of Guangxi's"two mountains"showed a relatively consist-ent trend with the actual value,and from 2021 to 2025,the energy conversion trend showed a continuous increase.Therefore,it is necessary to reduce the negative pressure of water and soil loss,industrial"three wastes"and car-bon emissions on the environment and reduce the functional loss of the ecosystem.
