摘要:

对稻田资源的生态价值和社会价值重视不足是稻田保护工作的最大缺陷，导致了稻田资源流失严重。通过构建稻田资源的价值体系，选取收益还原法、市场价值法、影子工程法、造林成本法、当量因子法、替代法等多学科相结合方法核算了稻田资源的经济价值、生态价值和社会价值，最终得出南京市稻田资源价值量为34892万元/hm2，其中经济价值、生态价值和社会价值所占的比例分别为332%、3026%和6642%，充分说明稻田资源的实物生产价值远远低于其生态价值和社会价值。在社会价值中，国家粮食安全价值（5808%）﹥社会保障价值（4192%）； 在社会保障价值中，养老保障价值（8408%）﹥就业保障价值（1592%），表明稻田资源的国家粮食安全价值和养老保障价值具有十分重要的作用。以2012年为基准年，南京市稻田资源的总价值量为333323亿元，是当年南京市GDP的4628%； 人均稻田资源价值量为52万元/人，是当年人均GDP的5878%，稻田资源价值巨大，研究结果为政府建立多层次的稻田保护补偿机制提供了科学依据，为具体经济补偿标准的确定提供了技术支撑。

Abstract:

Less attention on ecological value and social value of paddy resources is the biggest defect of paddy protection, leading a serious loss of paddy resources. Through constructing the value system of paddy resources, and using the methods of income assessment, market value, shadow engineering, the afforestation cost, equivalent factor, etc., this paper estimated the economic value, ecological and social values of paddy resources. The results showed that the value of paddy resources was 3,489,200 yuan / hm2, of which the economic value, ecological value and social value occupied 332%, 3026% and 6642%, respectively. Physical production value of paddy resources was much lower than the ecological and social value. For social value, the value of national food security accounted for 5808%, while the value of social security accounted for 4192%. For social security value, old-age security value (8408%) was more than employment guarantee value (1592%). It indicated that the value of national food security and old-age security both played a very important role. Taking 2012 as the base year, the total value of Nanjing paddy resource was 333323 billion yuan, occupying 4628% of GDP in 2012 in Nanjing. Per capita Value of paddy resources was 522 × 103 yuan, occupying 5878% of per capita GDP in 2012. The results can provide a scientific basis for the government to establish a multi-level compensation mechanism to protect paddy resources, and a technical support for the determination of specific economic compensation standard.
