| 摘 要： | 构建连续性生态网络已成为生物多样性保护、生态环境安全管理、游憩和历史文化资源保护的重要景观规划策略,其规划与管理已受到广泛关注.关键景观组分的识别是生态网络规划与管理的重点和难点,为解决这一问题,本文借鉴图论网络分析理论提出了景观中心度的概念及度量方法,并探讨了景观中心度在生态网络规划与管理中的应用内容和框架.景观中心度方法虽然可为景观规划与管理中关键景观要素的确定和连续生态网络的构建提供新途径,但仍需从指标的生态意义、实验数据的分析和简单通用的分析软件等方面对该方法进行验证和完善.

| Abstract: | Coherent ecological network (EN) construction has been considered as an important landscape planning strategy for biodiversity conservation, eco-environmental safety management, and resources protection of recreation, history and culture. Its planning and management attract extensive attentions from ordinary people to managers. To identify the key landscape elements is the keystone and the difficulty in EN planning and management. In order to solve this problem, the concept landscape centrality and its measurement were put forward in this paper, based on graph theory and network analysis theory, with its application aspects and framework discussed. It was considered that though the concept landscape centrality could supply a new approach to solve the problems in identifying key landscape elements and building coherent EN, further studies should be made on the ecological significance of centrality indices, analysis of experimental data, and development of simple and universal software, aimed to validate and improve this approach. |
