| 摘 要： | 研究区域生态系统定量评价方法对区域生态系统的建设与保护具有十分重要的意义。从放射源理论出发,首次将生态影响距离、生态源及生态影响效应的概念引入分析评价中,提出了区域生态系统的定量评价方法,并建立了基于景观空间格局的区域生态系统生态影响的定量计算公式。甘垛镇新庄片和横泾镇沿荡片的应用实例表明,该方法原理简明、结果直观,为区域生态系统的科学评价提供了定量评价方法。 |

| Abstract: | Study on the method of quantitative assessment for regional ecosystem is significant in constructing and protecting re-gional ecosystem. The concepts of eco-affecting distance,eco-source and eco-efficacy are led into regional ecosystem assessment for the first time based on the theory of the radioactive resource. The method of quantitative assessment for regional ecosystem is put forward,and the numerical formulas for impact of human disturbance analysis on regional ecosystem is established based on land-scape spatial pattern. The analysis results from the Xinzhuang region in Ganduo Town and Yandang region in Hengjing Town suggest that the method is a valuable uncomplicated tool with concise of conception and intuitional results. It could be widely used for quan-titatively scientific assessing the impact of human disturbance on regional ecosystem. |
| Keywords: | regional ecosystem landscape spatial pattern eco-affecting distance |
