Land fragmentation has become a serious obstacle to agricultural production, and land transfer and consolidation are traditionally emphasized as the two most effective solutions to this quandary. To identify the extent of land fragmentation accurately and systematically, this study selected the number of plots, the average size of plots, and the average distance between plots to calculate the land fragmentation index (LFI). Taking the Wuhan metropolitan area as a case study, this study examined the effectiveness of farmer-led land transfer and consolidation on land fragmentation. The main results are as follows: (a) most of the transferred plots and contracted plots were not spatially adjacent, suggesting that the tenants could not merge and consolidate both plots; (b) land transfer caused the LFI to increase by 2.85%, suggesting that land transfer had intensified the degree of land fragmentation to some extent; (c) if the transferred and contracted plots were non-adjacent or adjacent but unmerged and unconsolidated, then the LFI might increase or decrease; (d) if the transferred and contracted plots were spatially adjacent, merged, and consolidated, then the LFI decreased significantly.

Geographical Space

Identifying geographical spatial conflicts and optimizing development patterns are important prerequisites for eliminating the conflicts of geographical spatial conflict. The paper takes the Wuhan Metropolitan Area as an example. Using grid-scale data, we construct a multi-functional suitability evaluation index system for geographical space, starting from three dimensions: ecological protection, agricultural production and urban construction. The multi-index comprehensive evaluation method is used to measure the geographical spatial suitability level and identify the characteristics of geographical spatial conflict patterns. Three-dimensional Rubik's cube model is used to divide the space conflict types and optimize the partition. We found that the areas with suitable ecological protection functions and more suitable areas are mainly distributed near the waters and the Dabie Mountains and Mufu Mountains with relatively high altitude in Wuhan Metropolitan Area. Suitable areas for agricultural production functions are concentrated in the Jianghan Plain. Suitable areas for urban construction functions are concentrated around urban areas, established towns, and major transportation routes. Regions with high intensity of land and space conflicts are mainly located in the central and northwestern parts of the Wuhan Metropolitan Area. Regions with low levels of conflict are concentrated in the west, northeast, and southeast regions of the Wuhan Metropolitan Area. The degree of geographical spatial conflict in Wuhan Metropolitan Area can be divided into three primary zones and 12 secondary zones, which are intense conflict zone, general conflict zone, and weak conflict zone. Based on multi-functional perspective, identifying and analyzing the types of geographical spatial conflict will help locate the development direction of different conflict areas and provide theoretical and technical support for the optimization of geographical space.

The Impact

Green vegetation plays a vital role in urban ecosystem services. Rapid urbanization often tends to induce urban vegetation cover fragmentation (UVCF) in cities and suburbs. Mapping the changes in the structure (aggregation) and abundance of urban vegetation cover helps to make improved policies for sustainable urban development. In this paper, a new distance-based landscape indicator to UVCF, Frag, was proposed first. Unlike many other landscape indicators, Frag measures UVCF by considering simultaneously both the structure and abundance of vegetation cover at local scales, and thus provides a more comprehensive perspective in understanding the spatial distribution patterns in urban greenness cover. As a case study, the urban greenness fragmentation indicated by Frag was demonstrated in Wuhan metropolitan area (WMA), China in 2015 and 2020. Support vector machine (SVM) was then designed to examine the impact on the Frag changes from the associated factors, including urbanization and terrain characteristics (elevation and slope). The Frag changes were mapped at different scales and modeled by SVM from the selected factors, which reasonably explained the Frag changes. Sensitivity analysis for the SVM model revealed that urbanization showed the most dominant factor for the Frag changes, followed by terrain elevation and slope. We conclude that Frag is an effective scale-dependent indicator to UVCF that can reflect changes in the structure and abundance of urban vegetation cover, and that modeling the impact of the associated factors on UVCF via the Frag indicator can provide essential information for urban planners.

Ongoing global urbanization is imposing tremendous pressure on the eco-environment. Research on the coupling of the eco-environment and urbanization has important significance for the sustainable development of urban metropolitan. Looking at the Wuhan Metropolitan Area, which includes nine cities, as a case study area, this paper describes an empirical study done to uncover the interactive coupling relationship between the eco-environment and new-type urbanization in the urban metropolitan area from the perspective of eco-environment carrying capacity. The eco-environment carrying capacity evaluation index system was set up using the pressure-state-response (PSR) model, and then the coupling model was built. The results indicate that the eco-environment carrying capacity in the Wuhan Metropolitan Area is generally sustainable and has three grades. The quality of new-type urbanization in the nine cities in the Wuhan Metropolitan Area shows clear spatial heterogeneity. There are five types of the coupling relationship including moderate coordinated development, elementary coordinated development, reluctant coordinated development, edge of maladjustment, and mild maladjustment between the eco-environment carrying capacity and new-type urbanization level in the Wuhan Metropolitan Area. Therefore, this paper proposes corresponding policies from the aspects of coordinating the industrial division of labor, focusing on the eco-environment carrying threshold and strengthening policy guidance.
