Abstract

Large-scale mining activity is the major environmental issue, including water pollution caused by Acid Mine Drainage (AMD). Samarinda, which is located in the province of East Kalimantan, Indonesia, has open pits and acid contributing land as a source of AMD pollutants. The potential AMD pollution can be assessed by utilizing Geographic Information System (GIS) and Remote Sensing (RS), which are considered reliable tools for measuring, mapping, monitoring, and model making for an area. The variables used in this research are void distribution, land cover, soil type, rainfall, topography, water body, and groundwater. The integration of these variables is used to analyze the potential of AMD pollution to water bodies by acid contributing land. Meanwhile, the void distribution and groundwater integration data are used to analyze the potential of AMD pollution to groundwater by voids. The overlay method is employed to analyze the potential spatial patterns of AMD pollution in the study area. The results show the high potential of AMD pollution to water bodies, specifically in the districts of Samarinda Utara, Palaran, and Sungai Kunjang. The high potential of AMD pollution to groundwater is found in the south delineation area, namely Palaran, Loa Janan Hilir, and Samarinda Seberang districts, with low and medium groundwater depth categories (20 - 70 and 50 - 150 MBGL). The spatial pattern of AMD pollution was random with the geometric arrangement of AMD pollution in the form of clusters.

基于GIS和RS的印尼Samarinda酸性矿井排水污染潜力分析

大规模采矿活动是主要的环境问题，包括酸性矿山排水（AMD）造成的水污染。Samarinda位于印度尼西亚东加里曼丹省，其露天矿坑和产酸土地是AMD污染物的来源。潜在的AMD污染可以通过利用地理信息系统（GIS）和遥感（RS）进行评估，这被认为是测量、绘制地图、监测和建模区域的可靠工具。本研究中使用的变量包括孔隙分布、土地覆盖、土壤类型、降雨量、地形、水体和地下水。这些变量的整合用于分析酸性土地对水体造成AMD污染的可能性。同时，利用孔隙分布和地下水综合数据分析了孔隙对AMD地下水污染的潜力。采用叠加法分析了研究区AMD污染的潜在空间格局。结果表明，AMD对水体的污染潜力很大，特别是在Samarinda Utara、Palaran和Sungai Kunjang地区。AMD对地下水的污染潜力很大，位于南部划定区域，即Palaran、Loa Janan Hilir和Samarinda Seberang区，地下水深度分为中低两类（20-70和50-150 MBGL）。AMD污染的空间格局是随机的，AMD污染以集群的形式呈几何排列。

期刊介绍： Journal of Settlements and Spatial Planning (JSSP) is a biannual, peer-reviewed, open access journal, edited by the Centre for Research on Settlements and Urbanism, Faculty of Geography, Babeş-Bolyai University, Cluj-Napoca, ROMANIA. For the unrestricted access to potential subscribers all over the world the journal is published in English language and can be accessed electronically. The Journal of Settlements and Spatial Planning addresses mainly to geographers, young researchers and also to other specialists in adjacent fields of research that focus their attention on aspects related to settlements and spatial planning. On the other hand, it strongly encourages representatives of the public administration, who are responsible with the practical implementation of planning projects, to bring their contribution to the scientific field. Our journal seeks to publish original theoretical and applied research studies on a large range of subjects addressed to urban and rural settlements and spatial planning, as well as precise issues related to both of them. We welcome scholars to bring their contribution (original articles in basic and applied research, case studies) and increase interdisciplinary research on settlements and their spatial impact.
