Assessing recreation carrying capacity of the environment attributes based on visitors’ willingness to pay

Recreation carrying capacity (RCC) is one of the most important indictors used in measuring the usage limits for the forest park resources. However, the consensus has not been reached with respect to the RCC’s content and its measuring metrics. In this paper, we attempt to establish a new RCC theoretical framework based on the demand theory of the tourism product characteristics. In the process, the choice experiment and orthogonal design methods are used in questionnaire designs and the conditional Logit model is used for parameter estimates. More than 700 park visitors are surveyed for data collection at the Shenyang National Forest park of Liaoning province in China. The primary park attributes being considered encompass vegetation, coverage, water quality, number of rubbish on the park trail path, admission fees, and congestion. The carrying capacity threshold for each specific attribute is identified.     

基于变异系数和锡尔指数的中国区域经济差异分析

本文从中国三大经济区的划分入手,选取人均GDP作为测评指标,用变异系数和锡尔指数对1978~2008年的区域差异水平进行定量测度。结果表明:①全国范围内区域经济绝对差异不断拉大,相对差异有所缩小;②东部与中西部差异十分明显,而中西部之间差异不甚明显;③东部地区内部差异呈不断缩小趋势,中部呈波动中下降趋势,西部处于波动中,但总体变化不大。对造成该现象的原因作简要分析,认为主要原因有区域环境、要素投入、制度性因素。

民族地区民生科技需求意愿及影响因素

正确引导民族地区民众民生科技需求意愿,对提高民族地区科技配置水平、加速民族地区发展具有重要意义。以新疆为例,利用调查问卷数据构建Logit实证分析模型,发现民族地区民生科技需求意愿及影响因素不仅与非民族地区存在较大差异,而且民族地区城乡间异质性也较为明显。研究结果可为民族地区制定适宜的民生科技推广政策提供经验支撑。     

Dynamic land use and land cover changes and their effect on forest resources in a coastal village of Matemwe,Zanzibar, Tanzania

Recent land cover change estimates show overall decline of tropical forests at the regional and global scales caused by multiple social, cultural and economic factors. There is an overall concern on the prevailing land use practices, such as shifting cultivation and extraction of forest materials as agents of forests losses, but also new, emerging land uses are threatening tropical forests. Understanding of the long-term development and driving forces of forest changes are needed, especially at local levels where many decisions on forest policies and land uses are made. This paper addresses the importance of such information for improved estimates of forest dynamics by studying local level land cover and land use changes during the last 50–70 years in the Eastern African tropical island of Zanzibar, Tanzania. The paper discusses the role of traditional and new land uses mainly subsistence farming, tourism and government interference through tree planting, in the long-term development of the forests at the village level. The material for the study is gathered from the interpretation of archival maps and aerial photographs combined with contemporary digital aerial photographs. The analyses are based on the mapping, spatial sampling and spatio-temporal change trajectory analysis (LCTA) of forest land cover, forest land uses and settlement patterns with GIS and statistics. Six distinct forest land cover change trajectories were identified and these illustrate dynamic and heterogeneous nature of the forests. Closed forest cover has dominated throughout due to cyclical land use patterns, but over 70% of the land area has been continuously transforming between closed, semi-open and open land cover conditions. Land use turnover rates indicate that hardly any forest areas are left untouched from the forces, which remove and re-establish forest vegetation in the long run. Land cover and land use change trajectories are spatially fragmented in the studied landscape. Majority of forest loss-gain dynamics is caused by shifting cultivation, while forest losses are most dramatic along the coast, where traditional and new land uses meet and land uses pressures are highest. The study suggests that landscape change trajectory analyses, where contemporary and historical information on land uses and land cover changes are spatially linked, can provide valuable aspects into local level forest land use planning and management strategies. For the case study, the findings suggest the following key forest management strategies for consideration: (1) establishment of a protected forest/scrubland in participation with the local stakeholders, especially the farmers, (2) promotion of areas for permanent agricultural practices, while simultaneously introducing management controls in the traditional slash-and-burn farming areas, and (3) promoting new livelihood opportunities for the farmers, who have traditionally been dependent on forest resources, meanwhile introducing alternatives for fuel wood for cooking.     

The Considerations on the Development of Well-being Credit in Underdeveloped Areas of West China

党中央、国务院高度重视民生问题,并一直把关注民生、保障民生、改善民生摆在突出位置。同时,民生问题也是老百姓最关心、最直接、最现实的利益问题。而保障和改善民生离不开金融信贷的支持,切实加大对民生领域的信贷支持、大力发展民生信贷,对保障和改善民生具有重大的现实意义。本课题基于欠发达地区民生信贷现状,剖析其中存在的问题,从而提出完善民生信贷的措施及政策建议。
