农业和非农业土地利用的混合代表了全球南方城市化的新模式。这种混合物阻碍了土地利用效率的提高，使污染物难以实现集中处置，造成了土地资源的浪费和严重的环境问题。虽然已有不少研究对土地利用结构进行了研究，但大多都是描述性的，缺乏定量的考察和深入的机理分析。利用栅格土地利用数据，通过计算连接计数值并辅之以景观度量，研究了1990年至2015年中国地区土地利用结构的时空格局，并试图解释近年来土地利用结构的区域变化。结果表明，2000年至2010年，浙江、福建、重庆、广东等经济快速增长地区和一些大城市、矿业城市的土地利用结构较为复杂；2010年至2015年，中国中部地区土地利用结构较为复杂。此外，计量经济模型的结果表明，在土地规划和管理严格的地区，如长江三角洲和珠江三角洲的城市群，以及城市化水平较高的地区，混合土地利用可以得到缓解。此外，空间异质性分析的结果表明，严格的土地管理对降低东部中国地区的土地利用结构混杂程度起到了重要作用，而对中部地区中国的影响并不显著。这项研究的结果表明，应该对土地利用进行适当的规划和管理，以确保可持续发展。
The mixture of agricultural and non-agricultural land-use represents a new pattern of urbanization in the Global South. This mixture has hindered the improvement of land-use productivity and makes it difficult to achieve the centralized disposal of pollutants, which has resulted in the waste of land resources and serious environmental problems. Although many studies have investigated land-use mixture, most of them remain descriptive and lack quantitative examination and an in-depth mechanism analysis. Using raster land-use data, this paper examines the spatiotemporal pattern of the land-use mixture in China between 1990 and 2015 by calculating join counts values supplemented by landscape metrics, and attempts to explain the regional variations in land-use mixtures in recent years. The results show that, between 2000 and 2010, land-use was more mixed in fast-growing regions such as Zhejiang, Fujian, Chongqing, Guangdong, and some major metropolises and mining cities, and that, between 2010 and 2015, land-use was more mixed in Central China. Additionally, the results of econometric models reveal that mixed land-use can be alleviated in regions with strict land planning and management, such as urban agglomerations in the Yangtze River Delta and the Pearl River Delta, as well as in areas with high levels of urbanization. Furthermore, the results of a spatial heterogeneity analysis show that strict land management has played an important role in reducing the land-use mixture in Eastern China; however, it has not played a significant role in Central China. The findings of this study suggest that land-use should be appropriately planned and managed to ensure sustainable development.
