Abstract: |
Against the backdrop of ecological civilization construction, the integration of multiple
regulations, and the transitional period of national land spatial planning reform, how to optimize and
coordinate ecological protection and rural revitalization through village scale spatial layout has
become a key issue in national land spatial governance. This study takes Bayin Maodao Gacha, a
typical village in the ecologically fragile area of the Yellow River Basin in Dengkou, Inner Mongolia,
as the research area. Based on the results of the 2020 land use change survey in Dengkou, ArcGIS
software spatial analysis function and MCR model are used to conduct suitability zoning of the land
and resource utilization functions in the research area. Optimization plans are formulated by
overlaying the current situation of land and resource utilization, and technical support and theoretical
reference are proposed for the preparation of the "multi planning integration" plan in the research
area. Based on the definition of land use functional zones and the current land use status map in the
research area, combined with field investigations to confirm the status of the land parcels, the land
resources in the village area are divided into seven subcategories: forest ecological land, grassland
ecological land, water ecological land, other ecological land, village construction land, agricultural
production land, and agricultural production service land. Based on the MCR difference, referring to
relevant literature on spatial suitability zoning and the current status of land use in the study area, the
study area is divided into five categories: rural development area, farmland protection area, ecological
agriculture area, ecological control area, and ecological protection area. This study adheres to the
principles of “ecological priority, green development”, “people-oriented, respecting public opinion”,
and “conservation and intensification, adapting to local conditions”, and formulates strategies for
optimizing the spatial layout of the country. All types of land in rural development zones remain
unchanged, and village blank land is set up for future development of villages without occupying
arable land; the suitability of land construction in farmland protection areas is second only to that in
rural development areas. This area has multiple suitability between construction and development and
agricultural production, and is a gathering area for residential land and agricultural production land in
villages. According to the principle of prioritizing green development, agricultural production
activities should be carried out as much as possible in the region, while coordinating the relationship
between agricultural production and living land use. Based on the actual situation, there is no need to
adjust the types of land use in the region; the ecological agriculture area is a transitional zone between
ecology and production space, and is a key area for agricultural land consolidation and the
establishment of farmland protective forests. This optimization will adjust all scattered village
construction land in the region to agricultural production land, while keeping other land types
unchanged. Considering that human activities can easily affect landscape ecology, but agricultural
production land has both ecological and production functions, it is advisable to transform agricultural
production modes to minimize ecological and environmental damage; the current land use within the
ecological control zone is mostly various types of ecological land, which serves as a barrier to ensure
the ecological security of the research area. Optimize the adjustment of village construction landwithin the region to agricultural production land, and other ecological land to forest ecological land, while keeping other land types unchanged. In addition,
ecological restoration activities can be carried out in ecologically fragile areas such as sandy and saline alkali land; due to being located within the ecological
protection red line, ecological protection and restoration should be the main focus of the ecological protection zone. Agricultural production and villagers' daily
activities should be prohibited. Therefore, all agricultural production land, agricultural production service land, and village construction land in the area should
be optimized to forest ecological land. After following the optimization strategy for adjustment, the ecological land area of grassland and water remains
unchanged, while the ecological land area of forest land increases, and the areas of other types of land decrease. The current status of forest ecological land is
230.52 hm2, with an optimized area of 377.07 hm2, an increase of 146.55 hm2. The current areas of agricultural production land, agricultural production service
land, village construction land, and other ecological land are 4 190.52 hm2, 431.86 hm2, 125.7 hm2, and 440.34 hm2, respectively. After optimization, they have
decreased by 15.03 hm2, 0.25 hm2, 1.82 hm2, and 129.45 hm2, respectively. There are a total of eight expected and constrained indicators for implementing the
indicator system of the "Inner Mongolia Autonomous Region Village Planning Compilation Regulations" and the transmission of higher-level planning in the
research area. The optimization results of the MCR model meet the requirements of various control indicators such as the permanent basic farmland protection
red line, ecological protection red line, and village construction boundary. Compared with the current situation of land and resource utilization pattern, the
regularity and connectivity of the optimized land spatial layout have been significantly improved, effectively solving the problems of fragmented land use and
disorderly spatial layout in the research area. The research results can provide reference for the preparation of practical village planning in the study area that
integrates multiple regulations. |
