摘要 运用InVEST模型并结合实地调研结果，对云南10个典型低丘缓坡建设项目区开发前后生态系统水源涵养功能进行定量测算，比较分析不同类型项目区水源涵养功能的差异。结果表明，开发后项目区平均产水量和平均产水深度均低于开发前，城市建设区的产水总量高于工业区，下降程度也高于工业区;大部分项目区水源涵养总量均低于开发前，仅光华项目区水源涵养总量高于开发前，城市建设区的水源涵养总量高于工业区，工业区水源涵养量下降程度高于城市建设区;导致项目区开发前后水源涵养量变化的原因有土地利用结构、植被、地形、径流、降水、土壤等自然和人为因素，其中受土地利用类型影响较大;低丘缓坡开发导致区域生态环境受到干扰和破坏，但不同的开发模式和功能定位对其影响存在差异。因此在低丘缓坡开发过程中，应采取工程、监管、法律和经济等综合措施，实现低丘缓坡开发建设与生态保护的协调。

Abstract Using the InVEST model and the results of field investigations， the water conservation functions of the ecosystems before and after the development of 10 typical low-hill and gentle slope construction project areas in Yunnan were quantitatively measured， and the differences in water conservation functions of different types of project areas were compared and analyzed.The results show that the average water production and average water production depth in the project area after development are lower than before development，the total water production of urban construction areas was higher than that of industrial areas， and the decrease degree was also higher than that in industrial areas.The total amount of water conservation in most project areas is lower than before the development. Only the total amount of water conservation in the Guanghua project area was higher than that before the development，the total amount of water conservation in urban construction areas was higher than that in industrial areas， and the decline in water conservation in industrial areas was higher than that in urban construction areas.The reasons for the changes in water conservation before and after the development of the project area are natural and human factors such as land use structure， vegetation， topography， runoff， precipitation and soil， among which the land use

type had a greater impact.The development of low hills and gentle slopes had caused disturbance and destruction of the regional ecological environment， but different development models and functional positioning had different impacts on them.Therefore， in the development process of low hills and gentle slopes， comprehensive measures such as engineering， supervision， law and economy should be adopted to realize the coordination of the development and construction of low hills and gentle slopes with ecological protection.

生态系统的水源涵养功能主要体现在改善水文状况、调节区域水分循环等方面[1]。生态系统中的植被如森林、灌丛、草地对水源涵养功能发挥着巨大的作用，其通过林冠层截留、枯枝落叶层持水和土壤层蓄水来调节地表径流和补充地下水，在防治旱涝灾害、净化水质等方面具有至关重要的作用[2]。……
