Eco-compensation is an environmental economic instrument for internalization of external cost. Returning farmland to lake is one of the important parts of restoring wetland ecosystem function in the Yangtze River Valley of China. Whether the project of lake recovery can be successful depends on the compensation to the farmers who have lost their original benefits and contributed to the wetland ecosystem recovery by returning farmland to lake. Aiming at the wetland recovery of the Dongting Lake, the practical implementation of pro- grams of the lake recovery and flood control in this area has been challenged by the heavy task of population resettlement, so it is an ideal area for case studies to reach the academic objectives proposed as the above. Based on field survey and experimentation, this research evaluated the benefit losses of the resettled farmers and the increased values of ecosystem service functions caused by wetland recovery, and furthermore, the value of eco-compensation for relocated farmers was calculated by considering the combination of the farmers' compensation appeal. The value of eco-compensation for relocated farmers in the Dongting Lake area was 6084.5 yuan per household by synthetic analysis of the effects on wetland ecosystem restoration. Moreover, this article took Dongting Lake area as a case to study and explore the basic issues of the eco-compensation by returning farmland to lake, that was who should pay, who should be paid, how much the payment was and what the payment means was, which sought the mechanisms of wetland restoration eco-compensation and prompted the people's enthusiasms for ecological restoration. 展开更多

The fact that ecosystem services have values that can be quantified has been widely accepted in recent years. Part of the economic values of ecosystem services have been realized partly by ecological compensation of fiscal transfer payments at different levels, trade and consumption of leisure tourism and ecological products, and carbon sequestration forest funds sponsored by non-governmental capital. However, it remains difficult to realize the economic value of ecosystem services as industrial products and support the coordinated and sustainable development of nature, economy and society. To reveal the role of ecological compensation, consumption of biological products, leisure tourism and ecosystem services trading in realizing the economic values of ecosystem services, we analyzed the composition, transfer and consumption pattern of ecosystem services. In order to provide theoretical and technological support for inter-regional ecological compensation, ecosystem service industry development and ecosystem services trade, the concept of ecosystem services credit and key problems with ecosystem services trading are proposed. 展开更多

Optimization of land use structure consists of economic and social and ecological optimization.Applying the minds of system engineering and principles of ecology,this paper presents such thoughts:the optimal forest_coverage rate calculated according to the reality of a district is set as main standard of ecological rationality in the district;through considering the value of ecosystem services of the land with GREEN equivalent (mainly cultivated land and grassland)and based on the rule,GREEN equivalent,this paper introduces the area conversion between woodland and cultivated land,also between woodland and grassland;this paper establishes a multi_dimension controlling model of optimization of land use structure.In addition,a multi_objective linear programming model for optimization of land use structure is designed.In the end,this paper tests and verifies this theory of ecological optimization,taking Qionghai city in Hainan Province as an example. 展开更多
