摘要
深入且全面地分析景观组分的生态过程并探究其内部的生态环境循环机理,有利于从景观格局及其生态过程的角度为哈尼梯田文化景观在后遗产时代的长久性保护和可持续发展提供相关的实践根据。以红河哈尼梯田世界遗产地坝达片区为例,利用ENVI、Fragstats和ArcMap等软件对坝达片区的高精度历史卫星遥感影像数据进行解译和景观格局指数分析。结果表明:①景观格局在水平方向具有明显的分异现象,景观类型相对多样,景观破碎度较低且景观连通性较好;②林地景观和农田景观是显著优势景观类型,对景观格局在总体上起到控制作用;③优势景观类型在空间上呈条带状分布而弱势景观类型以散点状分布;④仍维持“四素同构”的景观格局,但出现了景观破碎化的问题。研究结果在一定程度上解释了红河哈尼梯田遗产地坝达片区的景观格局水平分布特征,为红河哈尼梯田遗产地的可持续发展提供思路。
A comprehensive and in-depth analysis of the ecological processes of landscape components and the exploration of their internal ecological environment cycling mechanisms will provide a practical basis for the long-term conservation and sustainable development of the Hani Rice Terraces cultural landscape in the post-heritage era,from the perspective of landscape patterns and ecological processes.This study takes Bada area,a world heritage site of Honghe Hani Rice Terraces as an example,and uses ENVI,Fragstats,ArcMap and other software to interpret the high-precision historical satellite remote sensing image data of Bada area and analyze the landscape pattern index.The results show that:①the landscape patterns of the Bada area were significantly differentiated in the horizontal direction,with diverse landscape types but a low degree of fragmentation;②forest landscape and farmland landscape play a significant controlling role in landscape patterns;③the dominant landscape types exhibit a belt-shaped spatial distribution,while the inferior landscape types are distributed in a scattered-point pattern;④it continues to maintain"four-element integration"landscape patterns,but is now experiencing issues of landscape fragmentation.To some extent,the research results explain the horizontal distribution characteristics of landscape patterns,and provide ideas for the sustainable development of Honghe Hani Rice Terraces World Heritage Site.
