Abstract
The purpose of land consolidation is to promote moderately sized agricultural operations, intensive land use, concentrated population living and agglomerated industrial development. Previous research has primarily been macro- or mesoscale studies based on land ledger data, and analyzed only the effect of land consolidation on landscape ecological changes, only the resource and economic effects, or social effects or environmental effects of land consolidation. Aimed at addressing these shortcomings, an empirical analysis on the micro-scale based on land use patch data rather than land ledger data was conducted. Then, comprehensive research on land consolidation projects by integrating landscape pattern analysis with production, living, and ecological benefit assessments was performed. Furthermore, the relationship between land consolidation projects and the “Three Concentrations” policy was considered. The results show that: (1) land consolidation has directly or indirectly improved landscape ecological patterns of the project area; and (2) land consolidation has clearly improved the balanced distribution of cultivated land and the concentrated distribution of construction land in the project area. These changes not only improve the living conditions of farmers but also meet the construction requirements of the “Three Concentrations” in the Shanghai metropolitan suburbs.
Highlights
Land consolidation refers to the activities to improve the efficiency of land use on lands that are used inefficiently and unreasonably, or on lands that are unused or damaged from the production and construction behavior as well as natural disasters [1]
In Shanghai, from land consolidation dominated by “Three Concentrations” in the mid-1990s [10] to land consolidation guided by a new type of urbanization in the early 2000s [11] and to land consolidation oriented toward ecological civilization since 2013 [12,13,14], land consolidation has stepped into a new stage of comprehensive, systematic, universal and multiple-type synergetic development
The area of low-efficiency construction land in the Heqing project area has been reduced by 19.3472 hectares (Table 6); in Langxia Town, the construction land area has been reduced by 6.5984 hectares, the number of patches has been reduced by 220, and the mean patch size has been expanded by 0.045 hectares (Table 7), which indicates that rural industrial land and residential land tend to be more concentrated
Summary
Land consolidation refers to the activities to improve the efficiency of land use on lands that are used inefficiently and unreasonably, or on lands that are unused or damaged from the production and construction behavior as well as natural disasters [1]. Johansen et al proposed a novel indicator-based approach to assess the collective impact of multifunctional land consolidation to apply land consolidation for increasing the multifunctionality of the landscape The index system they set up includes 25 specific indicators in five categories (farm economic indicators, environmental indicators, biodiversity conservation indicators, outdoor recreation indicators, and indicators for rural development) [44]. (3) The study of land consolidation patterns and applicability is gaining more and more attention This includes the pattern of rural residential area improvement [57,58,59], the pattern of low-efficiency industrial land consolidation [36], the pattern of country parks construction in the outskirts of metropolitan areas [60], the land consolidation pattern based on rural renewal [61], and the universal land remediation model [62]. A comprehensive research on land consolidation projects by integrating landscape pattern analysis with production, living, and ecological benefit assessments was performed. The relationship between land consolidation projects and the “Three Concentrations” policy to highlight the comprehensive value of the land consolidation projects was considered
