- Abstract:
-
Cultivated land use zoning has a guiding significance for the orderly development and utilization of the future regional space. The multidimensional analytical evaluation of cultivated land quality is an important way to expand the traditional evaluation theory of cultivated land quality and is the key to ensure the implementation of the zoning work. Taking the unified quality concept of ‘Trinity' as the theoretical basis and taking Huanghua, Hebei Province as the research area, we constructed a three-dimensional analytical evaluation framework of cultivated land quality integrated with ‘space-function-environment', and characterized the spatial correlation of three-dimensional quality by Spearman rank correlation coefficient and G* hot spot analysis tool. Finally, based on the above results, we carried out the cultivated land utilization zoning, and put forward the suggestions of differentiated management. The results showed that:(1)there were spatial differences in the cultivated land quality fractions in various dimensions in Huanghua; the high-value areas mainly distributed in the west and north of Huanghua, while the low-value areas mainly distributed in the southwest of Huanghua;(2)there was a strong spatial correlation effect between the cultivated land quality in various dimensions in Huanghua; there was a strong trade-off relationship between natural environment and social environment; spatial characteristics showed a strong cooperative relationship with scale and material production function; the distribution pattern of cold hot spots in different dimensions might be similar, but there might be spatial conflicts in the same dimension;(3)Huanghua was divided into five areas, namely production advantage protection area, leisure agriculture development area, economies of scale improvement area, fallow improvement area and potential function mining area. the characteristics of each cultivated land utilization area were different, so the cultivated land utilization and management should be carried out according to local conditions. These results of this study have practical significance for enhancing the operability of cultivated land utilization zoning, and can provide reference for optimizing the protection path of cultivated land utilization.
