Abstract

Abstract This study aims to investigate the dynamic pattern of landscape ecological units (LEUs) and analyse spatial variations of the ecological risk in Parangtritis coastal dune, Yogyakarta, Indonesia. A quantitative method was used in this research as part of landscape ecological analysis using a geographic information system. LEUs were interpreted by small format aerial photographs (SFAPs) and verified through field survey, then were calculated using the formula within grids to produce the ecological risk index (ERI) in the total area. According to the sub-class and class scenario, many LEUs showed changes in their landscape pattern. The ERI in the study area consisted of five levels (very low to very high), each of which was spatially varied. The ecological risk formed clusters coinciding with certain LEUs where fragility chiefly contributed to the sub-class scenario, while disturbance contributed to the class scenario.
利用高分辨率航空摄影对沿海沙丘景观的生态风险进行空间分析
摘要 本研究旨在调查景观生态单元(LEUs)的动态模式,并分析印度尼西亚日惹 Parangtritis 沿海沙丘生态风险的空间变化。作为景观生态分析的一部分,本研究利用地理信息系统采用了定量方法。通过小型航空摄影照片(SFAPs)解读低地单元,并通过实地调查进行核实,然后使用网格内的公式计算出总面积的生态风险指数(ERI)。根据子类别和类别情景,许多低地单元的景观格局发生了变化。研究区域的ERI包括五个等级(极低到极高),每个等级在空间上都有差异。生态风险形成了与某些低地单元相吻合的集群,其中脆弱性主要归因于亚类情景,而干扰则归因于类情景。

期刊介绍: Quaestiones Geographicae was established in 1974 as an annual journal of the Institute of Geography, Adam Mickiewicz University, Poznań, Poland. Its founder and first editor was Professor Stefan Kozarski. Initially the scope of the journal covered issues in both physical and socio-economic geography; since 1982, exclusively physical geography. In 2006 there appeared the idea of a return to the original conception of the journal, although in a somewhat modified organisational form. Quaestiones Geographicae publishes research results of wide interest in the following fields: •physical geography, •economic and human geography, •spatial management and planning,
