[目的
]
对流域生态系统产水功能进行定量评估及空间表达,为流域水资源优化配置,水资源可持续管理及提高生态效率提供科学支撑。[方法
]
以2015年大凌河上游汇水区作为研究区,基于权衡多重生态系统服务、保护与发展的决策支持系统模型(InVEST模型)中的水源涵养模块(Water Yield),对大凌河上游汇水区水源涵养功能定量评价,分析其空间分布特征,对水源涵养量进行归一化处理,识别其水源涵养等级。[结果

,水源涵养量空间异质性明显。②归一化处理结果表明,水源涵养较高等级区位于喀喇沁左翼蒙古族自治县中部、北部,水源涵养较低等级区位于内蒙古宁城县及敖汉旗北部、河北省平泉县。水源涵养中等级面积广泛,占据研究区面积的34.7%。③喀喇沁左翼蒙古族自治县、朝阳县西南部为重要水源涵养区,应加强水源管理与保护。[结论

土地利用类型、气候因子、土壤质地等因素对水源涵养空间异质性有重要影响,水源涵养量空间分布不均且差异显著。
[Objective] To evaluate water production function quantitatively and study its spatial expression of watershed ecosystem in order to provide scientific support for optimal allocation and sustainable management of water resources and improvement of ecological efficiency.[Methods] Taking the upstream catchment of Daling River as the study area
we firstly evaluated the water conservation service in 2015
and analyzed the spatial distribution characteristics using the water yield module of integrated valuation of ecosystem services and tradeoffs (InVEST) model. Then
the obtained water conservation evaluation results were normalized and divided into different classes.[Results] ① Total water conservation capacity of the upstream catchment in Daling River reached to 1.82×109 m3 in 2015
and it showed obvious spatial heterogeneity. ② The normalized results showed that high grade area of water conservation was located in the central and northern part of the Kalaqin Left Wing Mongol Autonomous County
while low grade area of water conservation was located in the northern part of Aohan and Ningcheng County of Inner Mongolia and Pingquan County of Heibei City. Moderate grade area of water conservation was widely distributed
which accounted for 34.7% of the study area. ③ The Kalaqin Left Wing Mongol Autonomous County and the southwest part of Chaoyang City was important water conservation area
which should be strictly managed and protected.[Conclusion] Factors such as land use type
climate and soil texture have important influences on the heterogeneity of water conservation
the spatial distribution of water conservation is uneven and the difference is significant.
