生态文化:中国先进文化的重要前进方向

生态文化是人类社会一种重要的先进文化,是中国先进文化的重要前进方向。在中国先进文化建设中,必须大力培育和发展生态文化。这是落实科学发展观,实现经济社会全面协调可持续发展的必然要求。     

上海市生态可持续发展评价研究

本文利用生态足迹法对上海市1985～2004年的生态足迹和生态承载力进行了研究，结果表明上海市入均生态足迹和生态承载力分别由1985年的1．9340hm^2、0．1582hm^2逐年增加至2004年的3．0459hm^2、0．5805hm^2，一而同期的入均生态赤字也由1．7958hm^2上升到2．6656hm^2。同时计算了万元GDP生态足迹，并预测了2010年的入均生态足迹和生态承载力。最后得出，上海市入口对自然资源的利用逐年增加，目前已超出了自然生态系统的生态承载力范围，现有的发展模式是不可持续的。     

基于生态足迹模型的可持续性度量研究--以吉林省大安市为例

针对吉林省大安市发展现状和存在的严重生态环境问题,运用生态足迹模型,采用多源数据,首次对大安市生态环境的可持续发展状况进行了定量研究;在此基础上,运用相对指标法对可持续发展的量化结果进行分级。研究表明,2001年大安市的生态需求大于生态供给,生态呈现“供不应求”的局面,人均生态赤字为0.56hm2,处于弱不可持续发展状态。     

Feminist Ecological Economics and Sustainability

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.      

厦门市绿地生态网络构建及优化策略

科学构建城市绿地生态网络，对区域生态安全、城 市可持续发展及生物多样性保护具有重要意义。基于AHP法 和GIS技术，定量分析厦门市自然生态本底，选取重要生态斑 块和廊道，采用最小费用路径法模拟潜在廊道，综合构建城 市绿地生态网络，并提出绿地生态网络优化策略。结果表明： 1)AHP法可整合区域生态、经济、人文和社会等资源，全面 客观评价现状生态斑块和廊道的重要程度；最小费用路径法可 根据生境分布特征科学模拟连通各斑块之间的潜在廊道；2)厦 门市西北部的生态基底适宜性、生态源地及廊道重要性、斑块 之间有效连通性均高于东北部及中部平原区；岛内斑块面积小 且分散，南北部存在断层现象，应适度增加踏脚石和连通廊 道；3)结合城市生态发展需求，提出构建“一片、一环、三 带、多廊道、多节点”的城市绿地生态网络。研究结果可为厦 门市绿地系统规划提供科学依据。

Analysis of Visitor Decision Making System When Visiting Natural Recreation Sites by Multinomial Logit Model

Multinomial Logit Model has analyzed the relationship between the frequency of visits to recreation areas and the motivational factors affecting the visits. Kastro Environment Preserving Site that is located in the Black Sea coast of Marmara region in Turkey, has been chosen as the site for this study. Kastro bay is a natural park that is visited only for recreational visits. The study has been conducted on a photogenic study group due to the proximity factor of Kastro bay close to Istanbul. Kastro bay is a popular recreational park due to its characteristic advantages such as a 200 m wide and approximately 2.5 km long beach and with its high quality vegetation. The vegetation type includes ash tree, oak tree, black pine, sand lily etc. Kastro bay is also the site for the Mediterranean seals (Monachus-monachus) which are at the level of extinction. Approximately 50,000 visitors visit the region during the months of July and August. It has been concluded that there is high direct correlation between the frequency of visits and the motivational factors. It has been determined that the visits are mostly based on the sea and the ecological tourism.Jel: O13, Q20, Q26, Q51, Q56, Q57     

配送计划的优化编制方法

讨论了在时间、距离和载重量等多种约束条件下，编制配送计划的优化方法。先给出配送问题的数学模型，并设计了一个带时间和距离约束条件的启发式算法来求解该模型，求得问题的近似解；然后再采用分枝定界法得到配送问题的最优解：最后，考查近似解与最优解在总的运行距离的相对误差，以此检验这个近似解的有效性。     

论我国区际生态补偿制度之构建

区域之间通过固有的地域联系发生环境关系而产生区际问题,要解决区际问题,应当建立区际生态补偿制度,设立区际生态补偿基金,明确补偿主体、资金来源及其管理分配方式。区际生态补偿制度蕴涵了公平的法律理念和良好的制度价值。     

我国自然保护区生态旅游初探

生态旅游是自然保护区可持续发展的必由之路。我国自然保护区面积广大,数量众多,类型多样,生态旅游资源丰富,发展生态旅游的条件得天独厚。在自然保护区生态旅游开发中应遵循保护与开发并重、三大效益组合最佳、统一规划、合理布局、重点开发、协调发展等原则。要研究和制定出全国自然保护区生态旅游发展战略,建立生态旅游示范区,进行合理分区,合理规划生态旅游景区,协调生态旅游自然环境保护与社区发展的旅游行为。在产品开发中,要努力开发和推广绿色旅游产品。同时,还应进一步加大旅游管理力度等,以实现对自然保护区的旅游资源及其环境的有效利用和保护以及旅游业的可持续发展。
