摘要
以"3S"技术为基础,运用市场价值法、机会成本法、影子工程法等,以山西省河曲县沙坪村为例,详细分析2010年土地利用生态系统的类型和特点,对生态系统服务价值进行估算,并采用价格修正系数进行修正。结果表明,沙坪村生态系统服务总价值为960.18×104元,是农村经济总收入的5.28倍。通过价值核算,以期为改变沙坪村和砖窑沟流域农业内部结构和土地利用格局、缓解人地矛盾、促进人与自然和谐发展提供科学依据,进而为绿色GDP的研究提供科学的评价方法和理论依据。
Taking Shaping village in Hequ County of Shanxi Province as an example, using the market value method, the opportunity cost method, the shadow project method and so on, the paper analyzes the types and characteristics of land use ecosystem, calculates ecosystem service value, and corrects the price with coefficient. The result shows that the total value of ecosystem services is 960.18 ×10^4 yuan, and 5.28 times the total earning of village economy. Through calculating service value, the research will be beneficial to change the internal structure of village agriculture and land-use patterns, ease the contradiction, divide the scientific basis for promoting harmony between man and nature, and provide scientific evaluation methods and theoretical basis for green GDP research.
