【摘要】：深化对耕地资源价值的认识,有助于实现耕地资源价值重建和耕地保护。本文以黄土丘陵沟壑区为研究对象,以宁夏回族自治区固原市原州区上黄试区为例,分析了耕地资源的价值体系,提出耕地资源经济产出价值、社会保障功能价值以及生态服务功能价值的估算方法,并对上黄试区1982年、2000年和2010年耕地资源价值进行了测算。结果表明:治理前(1982年),上黄试区耕地资源的价值较低,仅为4.37万元·hm-2 ,治理期(1982—2000年)和退耕期间(2001—2010年),上黄试区耕地资源价值有较快增长,两时期末的2000年和2010年分别达到24.13万元·hm-2 和56.47万元·hm-2 。其中耕地资源的经济产出价值增长最快,1982年仅为0.87万元·hm-2 ,2000年和2010年分别达到10.96万元·hm-2 和21.86万元·hm-2 ,耕地资源经济产出价值占耕地资源价值比重也由1982年的19.91%提升到2000年和2010年的45.41%和38.71%;其次是耕地资源社会保障价值,1982年耕地资源社会保障价值为2.11万元·hm-2 ,2000年和2010年分别达到8.37万元·hm-2 和25.00万元·hm-2 ;整个研究期间,耕地资源生态服务功能价值不断提升,1982年为1.39万元·hm-2 ,2000年和2010年分别达到4.81万元·hm-2 和9.62万元·hm-2 。不同时期耕地资源价值变化的影响因素不同,上黄试区综合生态经济治理期间(1982 2000年),科技因素对耕地资源价值提升起主导作用;而退耕期间(2001 2010年),政策因素对耕地资源价值提升起主导作用。为促进上黄试区耕地资源价值进一步提升,需要进一步对现有部分坡耕地实施退耕,提高耕地质量和集约化水平,实施农业节水工程建设等措施,提高耕地资源化配置水平。
[Abstract]:Deepening the understanding of the value of cultivated land resources is helpful to realize the value reconstruction of cultivated land resources and the protection of cultivated land. This paper takes the loess hilly and gully region as the research object, and takes the Shanghuang test area of Yuanzhou District of Guyuan City, Ningxia Hui Autonomous region as an example. This paper analyzes the value system of cultivated land resources, and puts forward the methods of estimating the economic output value, social security function value and ecological service function value of cultivated land resources. On 1982, 2000 and 2010, the value of cultivated land resources was calculated. The results showed that the value of cultivated land resources in Shanghuang test area was only 43,700 yuan 路hm-2 before management (2010), and the value of cultivated land resources was only 43,700 yuan 路hm-2. The value of cultivated land resources in the Shanghuang trial area has increased rapidly during the period of 1982-2000) and the period of returning farmland from 2001 to 2010. By the end of 2:00, on 2000 and 2010, it reached 241,300 yuan 路hm-2 and 564,700 yuan 路hm-2 respectively. The economic output value of cultivated land resources increased the fastest, only 8,700 yuan 路hm-2 on 1982, 109,600 yuan 路hm-2 on 1982 and 218,600 yuan 路hm-2 on 1982, respectively. The economic output value of cultivated land resources increased from 19.91% in 1982 to 45.41% and 38.71 in 2000 and 2010, followed by the social security value of cultivated land resources, which was 21,100 yuan 路hm-2 in 2010, 45.41% and 38.71 in 2010, respectively. In 2010, it reached 83,700 yuan 路hm-2 and 250,000 yuan 路hm-2 respectively; During the whole study period, the value of ecological service function of cultivated land resources was continuously improved, which was 13,900 yuan 路hm-2 in 1982, 48,100 yuan 路hm-2 in 2000 and 96,200 yuan 路hm-2 in 2010. The influencing factors of the change of cultivated land resources value were different in different periods. During the period of comprehensive ecological economic management in Shanghuang test area, in 2000, scientific and technological factors played a leading role in promoting the value of cultivated land resources. In 2010, the policy factors played a leading role in promoting the value of cultivated land resources. In order to promote the further improvement of cultivated land resource value in Shanghuang trial area, it is necessary to further implement the conversion of existing sloping farmland. We should improve the quality and intensive level of cultivated land, implement the construction of agricultural water-saving projects, and raise the level of cultivated land resource allocation.
