Study of the Vegetation Eco-Compensation Standards on County Scale in Qinghai Lake Watershed

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/ hm² of mountain shrub, 5303yuan/ hm² of arable land, 5028yuan/ hm² of valley shrub, 4923yuan/ hm² of alpine meadow, 4898yuan/ hm² of lakeside marsh, 4525yuan/ hm² of alpine marsh, 4507yuan/ hm² of temperate grassland, 4058yuan/ hm² of valley marsh, 2575yuan/ hm² of sparse vegetation on alpine flowstone slope. The eco-compensation value on the County scale are respectively 47.61 ×10⁸ yuan for Tianjun County, 29.18 × 10⁸ yuan for Gangcha County, 5.63 × 10⁸ yuan for Haiyan County, and 16.31 × 10⁸ yuan for the Gonghe County, the total vegetation compensation value of the Qinghai Lake Watershed is 98.73 × 10⁸ yuan.
