Abstract:
By means of the statistical method of forest economics and establishment of calculating index system, through quantification of the ecological and economic benefit values, the total value of ecological and economic benefit of the grassland shelterbelts on the Korqin Sandy Land, was objectively evaluated. It was shown that the total effect coefficient of the shelterbelt system on sandy grassland was 4.57, and the total effect coefficient of ecological benefit 42.85, the total effect coefficient of economic benefit 3.29. The transformed value of ecological benefit was 470.79 yuan/hm2 annually, and the annual income of economic benefit 770.72 yuan/hm2 in the grassland shelterbelt system on the Korqin Sandy Land. By arranging the basic indexes of ecological and economic benefit in order of its importance it indicated that priority should be given to ecological benefit in the desertificated and semi-desertificated areas on the Korqin Sandy Land.
