Identifying the driving forces that cause changes in forest ecosystem services related to water conservation is essential for the design of interventions that could enhance positive impacts as well as minimizing negative impacts. In this study, we propose an assessment concept framework model for indirec...
Population per unit area reflect the natural ecological system types of land use patterns, negative effects of grassland, woodland, woodland ecosystem has the function of water conservation, helped clear of flow mechanisms in aquatic restoration, grassland belonging to nitrogen and phosphorus losses ...
