摘要

摘要: 四川华蓥山中段地区水流失比较严重，供需矛盾突出，水环境持续恶化，不但影响到居民正常的生产和生活，而且严重影响了该地区国民经济的建设和发展。通过野外调查和综合分析现场收集的资料，总结出华蓥山中段地区地下水资源量流失情况：该区每年流失的水资源量约为0.914 4亿m3，且华蓥山褶皱西翼水流失总量大于东翼，而西翼北端是区内水流失量最严重的区域，其水资源量流失的影响因素主要为气候、社会发展及人类活动等。

Abstract: Huaying mountain, a karst mountain area, is located in the east part of Sichuan Province. The study area is about 1,500 km2, with its middle part bestriding the east and west wings of Huaying mountain anticline which presents a north-east trending silver shape. Over the anticlinal wings, karst strata and non-karst strata alternately distribute. Bounded by non-karst strata constituting the aquitard, groundwater in the area mainly occurs in strip-shaped carbonate rock formations. Restricted by the conditions of stratum exposure, the karst water migrates in the direction from the southwest to the northeast. Since the 1980s, groundwater resources in middle regions of Huaying mountain area have drastically declined. The loss of the karst water has heavily affected both water supply to the local communities and development of regional economy. This paper discusses the factors and the quantity of water resources loss in the area. Through integrating analytical results of field survey and desktop study, the factors that have impacted on the water resources reduction, including climate change, social economic growth and human engineering activity, were identified. Among them the decrease of rainfall and the steep topography in mountain region have resulted in the shrink of water replenishment. In addition, social economic growth and expansion of human engineering activities both have led to great water consumption. According to the division method of karst water system, the groundwater units for water resources assessment in the study area were divided. On this basis, the water balance method was used to calculate the amount of water resources loss each year which is about 91.44×106 m3. The volume of water loss in west wing of Huaying mountain is larger than that of the east wing. Moreover， the north part of the west wing has suffered from the most serious water loss in the area. By discussing the relationship between social, economic, environmental and water resources loss, this paper provides a certain basis for the comprehensive assessment and sustainable development of water resources in the study area.
