Taking Baoshan City of Yunnan Province as an example, the spatial distribution of regional water conservation function was evaluated based on Budyko water balance model using the global monthly precipitation, temperature data (900 m resolution), MOD17A3 NPP data and HWSD-v1.2 soil data. The results show that the spatial distribution of water conservation is mainly affected by the uneven spatial distribution of precipitation, and the barrier of Gaoligong Mountain plays an important role in water vapor distribution. The unit water conservation and total water conservation of different land types are forest > shrub grassland > cultivated land > water area > construction land. It is very important to enhance the ability of forest conservation. The most important area of water conservation in the study area accounts for 14% of the total area and is concentrated in the west side of Gaoligong Mountain. The water conservation capacity of most areas in the east side is relatively low, which exerts much stress on water conservation.

以云南省保山市为例, 利用CHELSA全球月降水量和月平均气温数据(900 m分辨率)以及MOD17A3 NPP数据和HWSD-V1.2土壤数据, 基于Budyko水平衡模型, 定量地评估区域水源涵养功能的空间分布状况。研究结果表明, 研究区的水源涵养量空间分布主要受降水空间分布不均影响, 其中高黎贡山的阻隔对水汽分布起重要作用; 不同地类的单位水源涵养量和总水源涵养量排序均为森林>灌草地>耕地>水域>建设用地。森林的保护和维持对区域水源涵养能力的提升至关重要。研究区水源涵养极重要区占市域面积的14%, 且集中于高黎贡山西侧, 东侧大部分区域水源涵养能力较弱, 水资源涵养功能维持的压力较大。
