摘要
[目的]以河北省定兴县为例,评价县域生态景观规划对景观格局和生态服务功能的影响及变化原因。[方法]在分析定兴县生态景观规划前后生态景观的格局特点、形成原因的基础上,基于文献法、分析法、RS及GIS等技术手段评价景观格局和生态服务功能。[结果]耕地景观在整个系统中占主要地位,生态景观规划前后定兴县景观平均斑块面积、生态服务功能等都发生了较大变化。生态景观规划保证了区域景观多样性指数的提高,使整个景观系统的稳定性上升,同时生态服务功能也提高了5.5%。[结论]区域生态景观规划是一项多目标兼顾的系统工程,只有在众多目标之间达成一种相对平衡,才能实现区域的可持续发展。
[Objective]Taking Dingxing County of Hebei Province as an example,the impact of county ecological landscape planning on landscape pattern and ecological service functions and the causes of changes were evaluated.[Method]Based on the analysis of the pattern and causes of ecological landscape before and after the ecological landscape planning in Dingxing County,the landscape pattern and ecological service functions were evaluated based on literature,analysis,RS and GIS.[Result]The cultivated land landscape played a major role in the whole system.Before and after the ecological landscape planning,the average landscape patch area and ecological service function of Dingxing County had undergone great changes. The ecological landscape planning ensured the increase of regional landscape diversity index,and increased the stability of the whole landscape system,meanwhile,the ecological service function also increased by 5. 5%.[Conclusion]The planning of regional ecological landscape is a multi-objective systematic project. Only by reaching a relative balance among many objectives can regional sustainable development be achieved.
