通过对沧州地区深层地下水漏斗的发展历史及最新地下水资源量评价结果的分析,认为沧州地区深层地下水在长时间高强度开采后已经获得了可观的补给量。但是,近半补给量是不可持续的,必须减少开采量以应对地面沉降等地质环境问题。大规模... 通过对沧州地区深层地下水漏斗的发展历史及最新地下水资源量评价结果的分析,认为沧州地区深层地下水在长时间高强度开采后已经获得了可观的补给量。但是,近半补给量是不可持续的,必须减少开采量以应对地面沉降等地质环境问题。大规模开发利用浅层微咸水资源可为沧州地区增加近2×108m3/a的可利用资源量,还可以增加降雨入渗补给量,改良地下水质,是解决沧州地区缺水问题的重要途径。 展开更多

This research was to assess the sustainability of fisheries in Pangandaran, West Java. This fishery is an important one in the region, but is threatened by increasing over-exploitation which has led to a steady decrease in the production. In addition to over-exploitation problem, a record of tsunami disaster makes this fishery a unique case. This research, based on a set of primary and secondary data was carried out using the Rapfish analytical approach. Primary data were collected using a stratified cluster random sampling technique, where as many as 186 outboard fishing operators were selected. Meanwhile, relevant complementary data were solicited purposively from five employees of Pangandaran Marine and Fisheries Service. Following from the Rapfish approach, it was found through this research that sustainability levels of fisheries in Pangandaran fall into poor category. For all types of fisheries that exist in the region, almost all sustainability dimensions namely ecological, social, technological and ethical dimensions were scored below 50 of the 100 maximum values. This paper concludes with a suggestion, pointing out attributes that should receive government attention in order that the sustainability of the fisheries in the future. 展开更多
