摘要
长白山北坡流域内矿泉水资源丰富,查明水源涵养量并制定开采阈值,有利于流域内矿泉水资源的合理利用。基于InVEST模型分析了水源涵养量和影响因素;结合Logistic模型与生态基流量理论计算和评价了矿泉水开发阈值。结果表明:研究区水源涵养总量由2000年的14.0×10^(8)m^(3)增加到2020年的16.8×10^(8)m^(3),气候为水源涵养量的主要影响因素,控制了研究区88.2%的面积;植被覆盖度增加的区域表现为气候和土地利用共同促进水源涵养量的增长。推荐生态基流量为1.014~1.244 m^(3)/s,河源区和河流中下游的推荐开采系数分别为0.36~0.46、0.4~0.5,目前开发程度远未达到阈值,可以继续进行开采。本文明确了水源涵养量与矿泉水的关系,广阔的森林面积涵养了大量水源,高水源涵养量可以保证矿泉水的水量和水质,适宜开发利用,且开发阈值的划定有利于矿泉水的可持续发展。研究成果对长白山区的生态保护和矿泉水开发利用具有一定的参考意义。
Mineral water resources are abundant on the northern slope of Changbai Mountain in Jilin Province. Finding out the water conservation potential of this area is crucial to the rational development of mineral water resources. InVEST model is used to calculate water conservation and the impact factors, and Logistic model and ecological base flow theory are adopted to calculate and evaluate the development threshold of mineral water. The results show that the total amount of water conservation in the northern slope of Changbai Mountain increased from 1.4×10^(9)m^(3) in 2000 to 1.68×10^(9)m^(3) in 2020. Climate is the main influencing factor of water conservation, controlling 88.2% of the study area;however, climate and land use jointly promoted the increase of water conservation in the areas with increased vegetation coverage. The recommended ecological base flow is 1.014-1.244 m^(3)/s, and the recommended mining coefficients for the source area and middle & lower reaches of the river are 0.36-0.46 and 0.4-0.5, respectively. At present, the exploitation degree of mineral water is far below the threshold value, so the mining can be continued. In this paper, the relationship between water conservation and mineral water is clarified, vast forest area cultivated a large amount of water resources, and high water conservation can ensure the quantity and quality of mineral water, which is suitable for development and utilization. The demarcation of development threshold is conducive to the sustainable development of mineral water. The research results will have positive significance for the ecological protection of Changbai Mountain and the development and utilization of mineral water.
