Land-Use Classifying and Identification of the Production-Living-Ecological Space of Island Villages—A Case Study of Islands in the Western Sea Area of Guangdong Province

Abstract

Accurately identifying the rural production-living-ecological space (PLES) of different islands can help reveal their distinct natural resources and land-use situations, which is significant for the sorted management, subarea utilization, and protection of islands. At present, studies on the PLES of island villages are deficient. For instance, the existing land-use classification system is incomplete; the PLES is poorly identified; and the dominant function of multiple land-use types based on different island geomorphology types is insufficiently investigated. Therefore, a case study was conducted on the island villages of the western sea area of Guangdong Province, based on remote sensing, spatial analysis, and land classification, with field research and the relevant data. In this study, before establishing the PLES system, the islands were classified, including six bedrock islands, 10 sedimentary islands, and one volcanic island. When the PLES system of the island villages was classified, the ecological and utilized areas of the intertidal zone and neritic region should be combined with the island–continent part, and the distinct industrial types should be emphasized, before forming 22 secondary types of PLES. Furthermore, it is found that each island generally has its own dominant space and land-use type. Ecological space (ES) dominates the bedrock islands, and production space (PS) is prominent for sedimentary islands and volcanic islands. Forestland, aquaculture pond, and dryland are the prominent land-use types for bedrock islands, sedimentary islands, and volcanic islands, respectively. The rural residential lands are the main component of living space (LS) in all islands, and the most urban residential lands are distributed on the bedrock islands. The main driving factors for the formation and distribution of island rural PLES are the altitudinal gradient and geomorphic characteristics. The research shows that the main problems of PLES are that the intertidal zones are threatened by aquaculture ponds at various levels, and the development of LS in these islands is generally backward.

Spatio-Temporal Variation and Influencing Factors of the Coupling Coordination Degree of Production-Living-Ecological Space in China

“…The coupling coordination of PLES is an extension of the connotation of coordinating the man-land relationship and promoting sustainable development [ 2 , 10 , 11 ]. Previous studies on PLES mainly focused on PLES classification [ 15 ], index construction [ 2 , 16 , 17 , 18 ], pattern evolution [ 19 , 20 , 21 ], spatial conflict [ 4 , 5 ], spatial optimization [ 8 , 9 , 16 , 22 , 23 ], eco-environmental effect [ 6 , 24 , 25 ], and coupling coordination analysis [ 2 , 11 , 12 ]. Specifically, regarding the classification of PLES, previous scholars have completed abundant studies on land classification and evaluation systems based on different research perspectives [ 2 , 17 , 26 ].…”

Rural Transformation Development and Its Influencing Factors in China’s Poverty-Stricken Areas: A Case Study of Yanshan-Taihang Mountains

“…The countryside is a geographical complex with natural and human characteristics and multiple functions such as production, living, ecology and culture outside the built-up urban areas [1,2]. Since the 1950s, the continuous advancement of globalization as well as the rapid development of industrialization and urbanization have driven rural transformation from production-based to consumption-based, and then to multifunctional and globalized-based [3].…”

Evolution Characteristics and Formation Mechanism of Production-Living-Ecological Space in China: Perspective of Main Function Zones

“…Thus, land use change is a direct reflection of PLES change. Previous studies on PLES mainly focused on PLES theory [ 16 ], classification [ 36 ], pattern evolution [ 17 , 37 , 38 ], optimization coordination, and conflict regulation [ 39 , 40 ], whereas few studies explored the structural evolution characteristics of PLES based on MFZ. PLES inherits the strategic positioning in territorial spatial planning under the MFZ strategy and is reflected in the quantity and spatial layout of PLES [ 41 ].…”
