Abstract

In Indonesia, water resources management planning has done based on river area. But the problem is the calculation still based on population data with administrative boundary. This is caused by the lack of population data with watershed or river area boundary. Geographical Information System (GIS) is a tools to analyze, visualize and interpret data with spatial and geographic data. For this research, GIS is used to generate population data with watershed and river area boundary,then the result will used for domestic water demand calculation for Cisadane upstream watershed. For all district in Cisadane Upstream Watershed, the largest district in entire watershed are Cibungbulang, Leuwiliang and Nanggung. But the most dense population are Ciomas, Ciampea and Cibungbulang. The calculation using watershed boundary resulting significant difference from district boundary. With spatial data population using watershed boundary, domestic water demand calculation result can be more accurate than using all district population data.
基于空间数据人口的上游流域生活用水需求模型
在印度尼西亚,水资源管理规划是根据河流面积进行的。但问题是人口数据的计算仍然基于行政边界。这是由于缺乏具有流域或河流区域边界的人口数据造成的。地理信息系统(GIS)是一种利用空间和地理数据分析、可视化和解释数据的工具。在本研究中,利用GIS生成具有流域和河流面积边界的人口数据,然后将结果用于西沙丹上游流域的生活需水量计算。在上游流域的所有地区中,整个流域最大的地区是Cibungbulang、Leuwiliang和Nanggung。但人口最密集的是马马、马比亚和旗邦隆。流域边界计算结果与地区边界计算结果差异较大。利用流域边界的空间数据人口,生活需水量的计算结果比使用所有区域人口数据更准确。
