摘要：尺度效应是景观生态学研究的热点。为探究小尺度不同地貌景观粒度特征,基于2018年法国Pleiades卫星解译的土地利用数据,以贵州省喀斯特中山、峰丛峡谷、低山丘陵、峰丛洼地4种喀斯特地貌的典型乡镇为例,从斑块类型水平和景观水平两个方面研究乡村土地利用景观的粒度效应。结果表明:4个不同地貌的乡镇斑块数量、斑块密度和斑块形状指数随粒度增加均呈现出下降的趋势,而随粒度增加,斑块所占景观面积变化不突出。香农多样性指数和香农均匀度指数的尺度依赖性较弱,聚集度、连接度、蔓延度和分离度的尺度依赖性较强。不同景观类型的斑块指标粒度效应存在差异,不同地貌乡镇的斑块指标和景观指标的粒度效应存在差异。喀斯特特色地貌背景下,人类活动作用下的土地利用结构特点是形成喀斯特乡村土地利用景观粒度变化特征的重要因素。
The scale effect is a hotspot in landscape ecology research.In order to explore the granularity characteristics of different landforms in small scale,taking the typical towns in four different karst landforms(karst mid-mountain,peak-cluster canyon,low hill,peak-cluster depression)of Guizhou Province as examples,this paper analyzed the granularity effect of land use landscape from the aspects of patch type level and landscape level based on French Pleiades satellite data in 2018.The results showed that:NP,PD and LSI in four towns with different geomorphology showed a decreasing trend with increasing granularity,while PLAND presented a little change with increasing granularity.SHDI and SHEI had weak scale dependence,whereas scale dependencies of AI,COHESION,CONTAG and DIVISION are relative strong.The granularity effects of patch indices for different landscape types were different,and the granularity effects of patch indices and landscape indices were different in four towns in different landforms.The land use structure resulting from the action of human activities under the background of karst landform are important factors to form the granularity change characteristics of land use landscape in karst villages.
