The transformation and development is an inevitable problem for resource-based cities (RBCs). In the process of transformation, cities in various cities, regions, resource types and development stages are having shown commonality and uniqueness. However, little work has been done on the horizontal comparison between RBCs. This paper evaluates the transformation level of 81 RBCs in China from 2006 to 2017 and investigates the transformation effect of cities in different regions, different dominant resources and different development stages. The comprehensive index system incorporating economy, society and environment is established by using the improved TOPSIS method. The results indicate that the transformation effects of most RBCs are between 0.400 and 0.800. Generally speaking, the transformation effects of four economic regions are on the rise, especially in the western region, with an increase of 17.626% from 2006 to 2015. The transformation effect of RBCs in the eastern region is the highest, while that in the northeast is the worst. Regeneration cities’ transformation effect is the best, reaching more than 0.70 in 2017. The transformation effect of growth cities is the worst, but the growth rate is the highest from 2006 to 2015. There is a rising trend of the transformation effects for oil-based cities and coal-based cities, while the transformation effects of iron-oriented cities and rare earth-oriented cities are not obvious. 相似文献

The Crested Ibis(Nipponia Nippon) is endemic to Qinling Mountains of China and was once abundant over vast areas of north-east of Asia habitat.During the 20th century,however,the population declined greatly in numbers.Habitat quality used to be the main threat to this species but recent actions by the government and wildlife protection organizations have brought this under control.With the establishment of Crested Ibis Nature Reserve in China,conflicts between socio-economic development and Crested Ibis conservation have become more acute.How do we deal with the relation between Crested Ibis conservation and community development? In this study,the Crested Ibis Nature Reserve co-management model namely "companies + farmers + Nature Reserve" model is proposed and evaluated with demonstration investigation methods,including continuous six-year fixed-site socio-economic development data of surrounding community,company sales revenue data and monitored data of Crested Ibis Nature Reserve.The results show that farmers' income and conservation awareness increased greatly from 2003 to 2008; company sales revenue has increased by about 20% annually in the recent years; management level has noticeably improved in Nature Reserve,the scope of Crested Ibis habitat has expanded 50 hm2; chemical composition of habitat reduced year after year; and the number of Crested Ibis had been growing annually.At the end,the success of the model is evaluated,and problems in implementation of the model are discussed from the following aspects:management system,co-management concept,economic base of partners,marketing mechanism,technical capacity and so on. 相似文献

Under the target of the sustainable development,optimization of forestry industrial structure contains rationalization and advancement of forestry industrial structure in the traditional sense,as well as ecologicalization of forestry industrial structure.The connotation of optimization of forestry industrial structure is analyzed at first,and then the paper chooses the typical evaluation indexes from the three sides of rationalization,advancement and ecologicalization to evaluate the current situation of the regional forestry industrial structure.With the aid of the theory of fuzzy mathematics and information entropy,the paper establishes a fuzzy evaluation model which is based on information entropy for optimization of forestry industrial structure,and the evaluation model is applied in the study for the current situation of forestry industrial structure from 2000 to 2006 in Hubei province.The results show that the grade of forestry industrial structure is bad basically during the research,of which the overall level of forestry industrial structure of Hubei province is poor,the degree of utilizing forest resource is lower,and ecological environment in the forest region has been damaged to some extent.On this basis,the author presents the countermeasure to promote the optimization of forestry industrial structure. 相似文献

利用中国对外投资综合增长率和出口总额增量的时间序列数据,考察我国走出去战略实施对我国贸易扩张的积极作用,研究中对数据分别进行了单位根检验,并讨论变量之间的协整关系和Granger因果关系。研究发现:在长期,中国对外直接投资对出口存在创造效应,并且对外直接投资是出口贸易增长的Granger原因;在长期,中国出口增长同样是对外直接投资增长的Granger原因。中国对外直接投资促进了出口的发展,与出口的增长之间为互补关系。从理论分析与实证分析两个角度都得出了中国对外直接投资促进出口贸易的发展,优化出口商品结构的结论。 相似文献
