| ［目的］揭示区域生态农业的布局特征，探讨生态农业的承载力，以期为农业持续发展提供科学依据和参考意见。［方法］文章以河南省为例，通过空间基尼系数和最邻近指数反映生态农业的布局，同时采用投影寻踪建立模型来预测河南省生态农业承载力。［结果］河南省的郑州市和信阳市生态农业基尼系数较高，其他市区的空间基尼系数较小，整体上河南省生态农业呈弱集聚。河南省生态农业布局的最邻近指数不同，郑州、信阳、济源、周口、鹤壁、商丘、三门峡、平顶山和驻马店等9个市的最邻近指数小于1，呈凝聚型分布； 而洛阳、安阳、新乡、濮阳、漯河、南阳、开封、焦作和许昌等9个市的最邻近指数大于1，呈均匀型分布。此外南阳市的生态环境承载力最大，信阳市的农业资源承载力最大，应加大该地区农业生态的开发力度，科学规划，持续发展，而郑州市的生态农业承载力均较低，现阶段应加强开发保护力度，促进可持续发展。［结论］河南省生态农业布局和承载力呈区域差异，今后应充分考虑各市区的实际特征和发展潜力，促进其持续发展。 |

| Abstract: |
| To reveale the layout characteristics of regional ecological agriculture and explore the carrying capacity of ecological agriculture, in order to provide scientific basis and reference opinions for the sustainable development of agriculture. Taking Henan province as an example, the paper reflected the layout of ecological agriculture through the space Gini coefficient and the nearest index, and used projection pursuit to establish a model to predict the carrying capacity of ecological agriculture in Henan province. The results showed that the Gini coefficient of eco agriculture in Zhengzhou city and Xinyang city of Henan province were higher, and the spatial Gini coefficient of other urban areas was relatively small. As a whole, the eco agriculture of Henan province showed a weak concentration. The nearest index of eco agriculture layout in Henan province was different, and the nearest indexes of 9 cities such as Zhengzhou, Xinyang, Jiyuan, Zhoukou, Hebi, Shangqiu, Sanmenxia, Pingdingshan and Zhumadian were less than 1 and they were aggregated; while Luoyang, Anyang, and Xinxiang were the most neighboring indexes of the 9 cities, including Fuyang, Fuyang, Luohe, Nanyang, Kaifeng, Jiaozuo, and Xuchang, were greater than 1 and were distributed in a uniform manner. In addition, Nanyang city had the largest ecological environment capacity. Xinyang city had the largest agricultural resources. It should increase the development of agricultural ecology in the region, scientific planning, and sustainable development, while Zhengzhou city′s ecological agricultural carrying capacity was relatively low. We should strengthen the development of protection and promote sustainable development. The layout and carrying capacity of eco agriculture in Henan province were regionally different. In the future, the actual characteristics and development potential of each urban area should be fully considered to promote its sustainable development. |
