补充资料：景观生态学
| 景观生态学 landscape ecology 研究景观的结构、功能和动态的科学。例如从某地的航片上可清晰地看到森林、草地、河流、城镇等相互作用的生态系统聚合而成的景观。景观中观察到的空间格局，包括种类、大小、形状、轮廓、数目和它们的空间配置，来源于物理的、生物的和社会的力量之间的相互作用。对于景观结构中的空间格局及其变化，景观生态学制定出一系列定性和定量指标，如景观的镶嵌性、连接度、碎裂性、均匀度、丰富度、边缘度等，这些特征对生物种的分布、运动和持久性有很大影响。景观生态学的研究焦点就是景观空间格局对生物群体的各种影响以及其结构、功能和动态。景观生态学在农林牧渔、风景旅游、城市规划设计、矿区开发、环境规划及国土整治等许多领域有重要的实践意义。 |
