六盘山西缘前庄地区水资源特征及开发利用建议

Water resources characteristics in the Qianzhuang Area,west edge of the Liupan Mountains:Suggestions for development and utilization

【目的】六盘山西缘前庄地区因其特殊的地理位置与构造属性有着较为独厚的水汽条件,为了科学地认识前庄地区水资源特征,推进该地区生态文明建设及经济发展,填补六盘山西缘水资源基础资料,对该区进行水化学特征研究。【方法】采集具有类型代表性的水资源样品,对其离子组分、离子组分空间变化特征、水化学类型及水质进行分析,结合旅游地质资源研究成果,给出其利用开发建议。【结果】结果显示:前庄地区水资源锶含量较高,属于富锶水,大部分指标符合《生活饮用水卫生标准》和《地表水环境质量标准》;水体资源整体阳离子浓度呈现Ca^(2+)>Na^(+)>Mg^(2+)>K^(+)关系,阴离子浓度表现为SO_(4)^(2-)>HCO^(-)_(3)>Cl^(-)>CO_(3)^(2-),反映水体为淡水;从空间分布来看,水体的离子质量浓度随着海拔从低到高呈现出增加趋势;水体水化学类型由HCO_(3)-Ca型水、混合型水和Cl-Ca型水组成。【结论】结果表明:前庄地区水资源总体水质较好,从旅游地质资源开发角度建议山泉水做富锶天然矿泉水继续开发,径流水做包装饮用水开发,其余水体资源根据区域旅游地质资源规划及开发程度再进行相应调查研究、规划开发。研究成果可为前庄地区水资源的开发利用、整体旅游地质资源统筹规划、六盘山西缘水资源及地质环境研究提供基础资料。

[Objective]The Qianzhuang Area on the western edge of the Liupan Mountains has distinct water-vapor conditions due to its particular geographical location and tectonic characteristics.The hydrochemical characteristics are studied in order to scientifically understand the water resources' characteristics,promote eco-environmental conservation,and supplement the basic information about water resources on the western edge of the Liupan Mountains.[Methods]Representative water samples were collected,and their ionic components,spatial variation characteristics of ionic components,hydrochemical types,and water quality were analyzed.The analysis result combined with the scientific research achievements of tourism geological resources led to suggestions on water resources' utilization and development.[Results]The water resources in the Qianzhuang Area are strontium-rich with high strontium content,and most of the indicators are in line with the “Health Standard for Drinking Water” and “Environmental Quality Standard for Surface Water”;The general cation concentration of the water resources presents a relationship of Ca^(2+)>Na^(+)>Mg^(2+)>K^(+),and the anion concentration shows SO_(4)^(2-)>HCO^(-)_(3)>Cl^(-)>CO_(3)^(2-),demonstrating that the waterbody is fresh water;From the spatial distribution,the ionic mass concentration of the water body shows an increasing trend with the elevation from low to high;The hydrochemical type of the water body consists of HCO_3-Ca type water,mixed water,and Cl-Ca type water.[Conclusion]The overall waterbody quality of the Qianzhuang Area is good.It is recommended that the mountain spring water be developed as strontium-rich natural mineral water and the runoff water as packaged drinking water.The rest of the water resources should be studied and utilized according to the development plan of regional tourism geological resources.The research result provide essential information for the rational development and utilization of water resources in the Qianzhuang Area,the overall planning of tourism geological resources,and the study of water resources and the environment on the western edge of the Liupan Mountains.
