APPLICATION OF ANALYTIC HIERARCHY PROCESS TO ASSESSING THE ECOLOGICAL VULNERABILITY OF WETLANDS IN THE JIANGHAN PLAIN   总被引：5，自引：1，他引：4  

WANGXue-lei NINGLong-mei HUWang-bin 《中国地理科学(英文版)》2003,13(3):272-276

Wetlands in the Jianghan Plain are important components of wetland types in lake area in the middle and lower reaches the Changjiang (Yangtze) River and they fulfill many uses and functions related to hydrology,waste assimilation, ecosystem productivity and biodiversity. Owing to natural factors and human activities, especially excessive reclamation from lakes, the shrinking process of the lakes has been accelerated. Wetland ecosystem has shown the characteristics of vulnerability. According to the analysis of wetland ecological function in the Jianghan Plain, this paper presented an index system related to productivity, stability and environmental capacity. By using the method of Analytic Hierarchy Process, we computed the values of the relative weights of the indexes, and evaluated the vulnerability level of the wetland ecosystem by the method of multi-indexes. The case study showed that the fragile extent of wetland ecosystem in the Jianghan Plain is 5.6. This means that the wetland ecosystem in the Jiang-han Plain is laid to the state of middle vulnerability. Therefore, the wetland conservation and eco-rehabilitation in the JiangJaan Plain should be paid attention to.  相似文献

JINFeng-jun 《中国地理科学(英文版)》2003,13(2):97-103

It is very important to establish cooperative mechanism to guarantee all members to develop their e-conomies in the Yellow Sea Rim. In this paper, the development strategies ofshipplng centers and transportation networkare discussed based on economic giobalization tendency. The results argue that a united transportation network should bebuilt in order to promote the economic competition of Northeast Asia in the world. As a key component of the economiccooperation, a hierarchical shipping centers network should be established with Hong Kong, Shanghai, Pusan, Koho,and Tokyo as cores. The authorities of China, Japan, R. O. Korea and D. P. B. Korea should make more efforts tobuild a set of cooperation institutions based on raising the transportation efficiency.  相似文献

分析了技术要素按贡献参与分配的基本依据和存在问题，提出了技术要素按贡献参与分配的建议：1．在企业分配领域，鼓励技术要素以多种形式参与收益分配，鼓励体制创新，推进技术股份化。2．在政府分配领域，政府财政科技投入比例与其科技发展对经济贡献增长率挂钩，科技财税政策与产业政策、税源经济吻合，营造科技奖励的软环境。3．在社会分配领域，充分发挥技术评估部门和行业管理部门的作用，对进入技术市场的技术的成熟度和科技含量进行有效的测试和监管，保证技术商品的品质；技术交易当事人应具诚信态度和法制观念；重视中介的作用，把技术市场搞活。  相似文献   

一定要把人类的牧地变成鲸类的墓地？     

蔡燕雯 《海洋世界》2006,(9):6-13

谁操纵了鲸类的命运 鲸（Whale），地球上现存最大型的动物，也是最大型的哺乳动物，曾经广泛分布在世界各大洋的海洋霸主，但它们在用现代科技武装起来的人类面前，再也强大不起来了。如今，徘徊在灭绝边缘的鲸类除了面临海洋污染、船舶撞击、噪声污染、渔业误捕和渔网缠绕等因素造成的危险外，更主要的威胁来自于捕鲸船的围猎。  相似文献

我国土地利用总体规划编制的理念与思考   总被引：2，自引：0，他引：2  

臧俊梅  王万茂 《国土资源》2006,(10):34-37

对我国规划理念的再思考 从本质上说,土地利用规划主要是从社会经济发展角度考虑,为公众利益服务的,它是一种政府的公共管理行为.但由于种种原因长期以来规划在实际工作中并未起到其应有的作用,"规划低效论"、"规划无用论"的说法更是加重了规划在实施层面上的难度.形成这种看法从根本上分析首先是人们对规划本质及规划问题认识不统一,各级政府尤其是领导在规划编制指导思想上的认识不足造成的.俗话说"只有正确的思想才能引导正确的行动",要进行规划修编,保证规划目标的实现,首先必须要对规划理念有一个正确而理性的认识.  相似文献
