【摘要】：耕地利用综合效益是衡量耕地生产能力和农业可持续发展的重要指标,对于保证国家粮食安全、保障社会稳定和维持生态平衡等方面具有重要意义。以内蒙古自治区为研究区,从耕地利用的经济效益、社会效益、生态效益三方面构建耕地利用综合效益评价体系,对内蒙古自治区近15年耕地利用效益时空特征进行分析。结果表明:2000—2014年内蒙古自治区耕地利用效益指数整体呈波动变化状态,经济效益指数呈上升趋势,社会效益、生态效益指数在波动中有所下降,综合效益指数略有上升。内蒙古自治区耕地利用效益具有明显的空间聚集性,表现为耕地利用经济效益、社会效益、综合效益指数空间分布具有一致性,较高水平地区主要分布在河套平原及自治区中部,生态效益指数高的地区主要分布在东部丘陵区。综合研究发现,在耕地利用效益中,经济效益、社会效益处于主导位置,生态效益受环境影响大,在今后的耕地利用过程中,应注重社会、经济、生态三大效益的协调发展。
[Abstract]:The comprehensive benefit of cultivated land use is an important index to measure the productive capacity of cultivated land and the sustainable development of agriculture. It is of great significance to guarantee the national food security, guarantee the social stability and maintain the ecological balance and so on. Taking Inner Mongolia Autonomous region as the study area, the comprehensive evaluation system of cultivated land use benefit was constructed from three aspects of economic benefit, social benefit and ecological benefit of cultivated land use in Inner Mongolia Autonomous region, and the spatio-temporal characteristics of cultivated land use benefit in the last 15 years were analyzed. The results showed that the arable land use benefit index of Inner Mongolia Autonomous region fluctuated in 2000-2014, the economic benefit index showed an upward trend, the social benefit, ecological benefit index decreased and the comprehensive benefit index increased slightly in the fluctuation of Inner Mongolia Autonomous region. The arable land use benefit of Inner Mongolia Autonomous region has obvious spatial aggregation, which shows that the spatial distribution of arable land use economic benefit, social benefit and comprehensive benefit index is consistent. The high-level areas mainly distributed in the Hetao plain and the central part of the autonomous region, and the areas with high eco-efficiency index mainly distributed in the eastern hilly areas. The comprehensive research shows that the economic and social benefits of cultivated land are in the dominant position, and the ecological benefit is greatly influenced by the environment. In the future, the harmonious development of the three benefits of society, economy and ecology should be paid attention to in the course of cultivated land use in the future.
