As a result of the groundwater utilization which exceeds its safe yield, the phenomenon of seawater intrusion is often found in some coastal areas. For this reason, the utilization of groundwater must not exceed its safe yield. This study aims to calculate the availability of groundwater and its safe yield and evaluate its utilization which does not exceed the safe yield. To achieve this purposes, groundwater availability is calculated using the static method by multiplying the area by the thickness of the aquifer and the specific yield. Utilization of groundwater for domestic, livestock and hotel requirement is carried out by multiplying the water demand for each of these sectors by the amount. Safe yield is calculated based on area width, groundwater fluctuation and its specific yield. The groundwater resources potential of research area amounted to 648,960,234 m³/year, while the safe yield was 127,702,334 m³/year. Utilization of groundwater for domestic, livestock and hotel requirement is 23,062,023 m³/year, so that the use of groundwater to meet domestic, livestock and hotel reqirement has not endangered the availability of groundwater. However, for Batang District, groundwater utilization has almost reached half of its safe yield.

巴塘县沿海海水入侵预测中家庭、畜牧业和酒店用水的安全产量要求

由于地下水开采量超过安全量，一些沿海地区经常出现海水入侵现象。因此，地下水的利用量不得超过其安全产量。本研究旨在计算地下水的可利用性及其安全产量，并评估其在不超过安全产量的情况下的利用情况。为了实现这一目的，地下水可用性是使用静态方法通过将面积乘以含水层厚度和比产量来计算的。生活用水、牲畜用水和酒店用水的地下水利用量是通过将每个部门的需水量乘以该用水量来计算的。安全产量根据区域宽度、地下水位波动及其比产量计算。研究区地下水资源潜力为648,960,234 m ³ /年，安全产量为127,702,334 m ³ /年。生活、畜牧和宾馆用水需求地下水利用量为23,062,023 m ³ /年，因此利用地下水满足生活、畜牧和宾馆用水需求并没有危及地下水的可利用性。但对于巴塘区来说，地下水利用率已接近安全产量的一半。
