摘要
杨家杖子是葫芦岛新建经济开发区,其因前期矿产资源的过度开发利用,开发区内经济、环境、卫生等亟待发展,水资源短缺成为了制约经济等发展的主要因素。开发区内赋存有孔隙水、风化裂隙水及岩溶裂隙水,采用补给量法及排泄量法计算地下水资源量,并进行水均衡分析及可开采量计算。区内地下水资源总补给量为210.87万m3/a,总排泄量294.98万m3/a,地下水处于负均衡的状态,可开采资源量为155.76万m3/a。对于岩溶区,在20%、50%、75%不同保证率下,可开采量分别为103.46、86.6、75.38万m3/a。结合现状开采量,提出水资源开发利用及保护措施。
YangJiazhangzi is an economic development zone, located in HuLudao. Because of excessive exploitation and utilization of mineral resources in early days, the development of economy, the environment and the health in development zone is urgent, and the water resources become the primary factor restricting economic development. The groundwater in Yangjiazhangzi area consists of pore-water valley, bedrock fissure water and karst fissured water. The methods of recharge and discharge are adopted to calculate groundwater resources, analyze water balance and calculate available water resources. The recharge of groundwater resources in Yangjiazhangzi is up to 210. 87×104 ms/a, the discharge of groundwater resources is 294.98 × 104 ma/a, and the available groundw- ater resources can be up to 155.76× 104 ma/a.. The groundwater is in negative state of equilibrium. In Karst areas, under 20%, 50%, 75% guarantee rate, the available exploitation yield are 103.46, 86. 6, 75.38 X 104 me/a, respectively. Combining with the existing exploitation amount, the countermeasures are put forward to develoo, utilize and protect water resources.
