太行山前南峪旅游区景观格局及其多样性研究

Study on the spatial pattern and diversity of the Qiannanyu tourism district in Taihang mountain area

为给太行山区资源的合理利用和可持续发展提供科学依据,对太行山前南峪旅游区的景观空间格局及其多样性进行了分析。选取的景观空间格局度量指标包括:斑块数量、斑块大小、斑块密度指数、破碎度指数、分离度指数、多样性指数、优势度指数、均匀度指数等。结果显示:前南峪景观以水土保持林和板栗林为主,二者面积占全区面积的92.24%,并且处在山坡的中坡和上坡位,在各景观中占绝对优势;景观面积、周长、斑块数、景观多样性指数较其他景观类型大,破碎度指数和分离度指数较其他景观小,对景观整体结构、功能及其变化的控制作用较强。其他景观类型处在山坡中下坡位,均匀度大小相似,增强了整体景观的多样性。这些结果表明,目前前南峪的景观格局基本合理,利于前南峪生物多样性的维持、生态环境的稳定和资源的可持续利用。

Scientific evidences are supplied for recourse rational use and sustaining development in Taishang mountain area. The landscape spatial pattern and diversities of Qiananyu in with gneiss of Taihang mountainous area were anaiyzed. Selected indices include patch number, patch size, patch density index, fragmentation index, separation index, diversity index, dominance index, evenness index etc. The results showed that Castanea mollissima and soil and water conservation forest were two main spatial type, whose area is occupied for 92.24 % and located in middle and up slope, taking a dominant position in whole of landscapes. Area perimeter, patch number, landscape diversity index are bigger than other places, but fragmentation index and separation index are smaller, and the control of each landscape elements on the whole landscapes structure, function and change of landscape are strong. Other landscapes located in middle and low slope, whose evenness index of similarity and diversity increases in the whole of landscape. These findings show that the present landscapes structures is reasonable in Qiananyu tourism district in term of diversity conservation and environmental stability and sustainable use of resources.
