Evaluation on Water Source Conservation Capacity of West Liaohe River Basin Based on Invest Model
The water yield model of integrated valuation of ecosystem services and tradeoffs (InVEST) model was employed to estimate the water source conservation capacity of West Liaohe River Basin and analyse its variation characteristics. The data included land use and land cover, average annual precipitation and potential evapotranspiration and so on. The results show that the total water yield of the Basin fluctuates obviously from 1990 to 2012. The actual evapotranspiration is decreasing. Water yield is becoming less and less. Water resources at the regional distribution is extremely uneven. The activities of returning farmland to grassland made the actual evapotranspiration and water yield decreasing. Dry coefficient increase. Ecosystem environment of West Liaohe River Basin is fragile and sensitive.
