| 摘 要： | 将农地生态功能分为土壤保持、涵养水源、净化空气、维持生物多样性、娱乐文化5类服务功能,运用直接市场法建立了评估模型,分别计算各项功能的生态服务价值,然后综合计算损失农地的生态价值,并以陕西省为例,计算得出2000～2009年陕西省损失农地的总生态价值为636 636.53万元。提出了合理保护农地的对策建议:正确认识农地的生态效益,科学评估农地价值;优化产业结构,促进农地集约利用;因地制宜,合理规划农地利用;多方合作,建立农地共同保护责任机制。

| Abstract: | We divide the the ecological functions of farmland into five types:soil conservation,water conservation,air purification,maintenance of biological diversity,entertainment and culture.Using the direct method of market evaluation,we establish the assessment model,to calculate the ecological service value of various functions,respectively,and then calculate the total loss of ecological value in farmland.Taking the case of Shaanxi Province,we calculate the total loss of ecological value in farmland in Shaanxi Province during the period 2000-2009 at 6 366.365 3 million yuan.Finally in order to rationally protect farmland,we put forth the following recommendations:correctly understanding the ecological benefit of farmland,and scientifically assessing the value of farmland;optimizing the industrial structure,and promoting intensive use of farmland;taking actions that suit local circumstances,and conducting rational planning of farmland use;strengthening multilateral cooperation,and establishing the common protection accountability mechanism of farmland. |
