Study on Land Consolidation Zoning in Hubei Province Based on the Coupling of Neural Network and Cluster Analysis

Abstract

Land consolidation zoning is the basis of land reclamation planning and provides a precondition for land management work. Zoning is beneficial to scientific decision-making regarding the use of cultivated land resources, and helps to ensure the quality and production level of cultivated land. Hence, land consolidation zoning is of national significance in terms of safeguarding food security. In this paper, an indicator system for land evaluation and zoning is described based on indicators of natural ecological conditions, socioeconomic conditions, land-use conditions, and the land consolidation potential of Hubei province. The application of self-organizing maps and Hierarchical clustering results in 11 and 12 categories, respectively. After comparing and adjusting these results according to the real situation and key points in the land consolidation of each zone, seven integrated categories are determined. Finally, the land consolidation zoning scheme for these seven integrated partitions is shown to be suitable for Hubei province and in line with the real situation. The proposed scheme offers support for land remediation in a coordinated and orderly way, and provides a scientific basis for improving land utilization efficiency and grain production capacity in Hubei province.

Exploring the Effects of Land Use Changes on the Landscape Pattern and Soil Erosion of Western Hubei Province from 2000 to 2020

“…Moreover, the rate of change in land use types was relatively large from 2005 to 2010 and from 2015 to 2020 (Figure 13), which was related to the completion of the South-to-North Water Diversion Project, the Hanjiang Ecological and Economic Belt and the Yangtze Ecological and Economic Belt. Importantly, this was related to the completion of the South-to-North Water Diversion Project [63], the construction of the Han River Ecological and Economic Zone and the Yangtze River Ecological and Economic Zone [68], as well as the rapid development of the Yijing-Jing'en City Cluster and the Xiangshi-Shuishen City Cluster [69]. This finding is consistent with the research of Liu et al ( 2014) and Ning et al (2018) [47,61].…”

Quantitative Morphology of Polder Landscape Based on SOM Identification Model: Case Study of Typical Polders in the South of Yangtze River

“…SOM is commonly combined with quantitative indexes and applied in element identification, comprehensive evaluation, and scheme optimization in landscape architecture and related disciplines research. It can be applied to SOM to hierarchical classification studies of building form [ 35 ], building space [ 36 ], and land use [ 37 ] in terms of element recognition. When it comes to comprehensive evaluation, SOM is frequently used to analyze multifactor datasets and solve complex classification problems, such as a comprehensive analysis of tourist motivation and behavior in protected areas [ 38 ].…”

Spatiotemporal Differentiation and Balance Pattern of Ecosystem Service Supply and Demand in the Yangtze River Economic Belt

“…Second is the application of the balance between the supply and demand of ecosystem services. The connection between the supply and demand of ecosystem services has been applied from the aspects of ecological network spatial optimization [ 30 , 31 , 52 , 53 ], land regulation spatial zoning [ 54 , 55 , 56 , 57 ], ecological security pattern [ 50 , 58 , 59 , 60 , 61 ] and land ecological restoration [ 62 , 63 , 64 ]. The existing research results have laid a certain foundation for exploring the pattern of balanced supply–demand relationship for ecosystem services; however, there are still some improvements.…”
