Description
Summary:Eco-compensation is one of the focus and hot topics for contemporary scientific research, in which the compensation standard takes the most important part. Based on the remote sensing data, meteorological data and field investigation data, with the simulation of terrestrial net primary productivity (NPP) from CASA model, we estimate and inverse the vegetation eco-compensation standards by means of market price method and energy substitutions, the results show that: eco-compensation standard for each vegetation type in the Qinghai Lake Watershed is respectively 5467yuan/ hm 2 of mountain shrub, 5303yuan/ hm 2 of arable land, 5028yuan/ hm 2 of valley shrub, 4923yuan/ hm 2 of alpine meadow, 4898yuan/ hm 2 of lakeside marsh, 4525yuan/ hm 2 of alpine marsh, 4507yuan/ hm 2 of temperate grassland, 4058yuan/ hm 2 of valley marsh, 2575yuan/ hm 2 of sparse vegetation on alpine flowstone slope. The eco-compensation value on the County scale are respectively 47.61 ×10 8 yuan for Tianjun County, 29.18 × 10 8 yuan for Gangcha County, 5.63 × 10 8 yuan for Haiyan County, and 16.31 × 10 8 yuan for the Gonghe County, the total vegetation compensation value of the Qinghai Lake Watershed is 98.73 × 10 8 yuan.
