The purpose was to highlight the role of vegetation in urban ecosystems and evaluate the effects of various human activities on urban annual oxygen consumption and carbon emission. Hopefully,the model would be helpful in theory to keep the regional balance of carbon and oxygen,and provide guidance and support for urban vegetation planning in the future. To test the UCOB model,the Jimei District of Xiamen City,Fujian Province,China,a very typical urban region,was selected as a case study. The results turn out that Jimei′s vegetation service in oxygen emission and carbon sequestration could not meet the demand of the urban population,and more than 31.49 times of vegetation area should be added to meet the whole oxygen consumption in Jimei while 9.60 times of vegetation area are needed to meet the carbon sequestration targets. The results show that the new UCOB model is of a great potential to be applied to quantitative planning of urban vegetation and regional eco-compensation mechanisms.展开更多

Here, we not only focus on Japan, but also pay more attention to challenges during this process. Based on a long-term field study on Sado Island, a less developed region in Japan, we attempt to describe how the government carries out environmental remediation towards the reintroduction of ibis （Species name） into the wild, and the conflict between ibis habitat restoration and farm management. We discuss the underlying reasons for this conflict and the negative effect on regional development. We follow policy improvements of the local government and related supplementary help carried out to fix the mismatch between the payment for ecological benefits and that lost by farmers in the pre-period. We conclude that the coordination of interest among different social groups is the key for success in ecological restoration and compensatory measures have to be made to meet the actual needs of the local groups. This case study in Japan can be applied to similar regions with poor environments and urgent environment restoration needs in China.展开更多
