Case investigation on the construction mode of rural landscapes in the Qinghai Tibet Plateau, Mengda National Nature Reserve.

It is vital and challenging to coordinate the protection of natural reserves with rural construction. The rural structure and function were divided during the creation of natural reserves on the Qinghai Tibet Plateau (QTP), throwing the rural structure and functional system and its constituent parts out of balance. According to current research results on the construction mode of rural landscapes, the creation of rural landscapes is unable to address the requirements of villages and encourage the creation of protected areas. Therefore, it has become urgently necessary to conduct research on the rural landscape construction model of the QTP natural reserve. This study focuses on the case study of the construction mode of rural landscapes in the Mengda National Nature Reserve (MNNR) in the QTP. The inherent hierarchical structure relationships between rural landscape types, units and elements were identified. The basic characteristics of residential, production and cultural landscapes and their interdependent structural relationships were described. According to the evidence collected from literature, the rural landscape complex model and spatial optimisation strategy in the MNNR were proposed. It is believed that the rural residential, production and cultural landscape structures of the MNNR cannot effectively realise its living, production and culture function. From a spatial structure level, a rural landscape construction model was proposed based on production landscapes, residential landscapes as characteristics and cultural landscapes as the source. This model is based on agricultural landscapes, features the village and village dwellings and originates from temple landscapes, forming a comprehensive landscape unit that relies on and supports each other among production, residential and cultural landscapes. Emphasising the structural construction of infrastructure, such as transportation roads, network routes, tourism routes and water and electricity networks between the system and the external environment, is essential for promoting the circular relationship between the agricultural community complex in Dazhuang Village and the external system. The model is beneficial to balance the relationship between the rural landscape structure and MNNR function and promote the sustainable development of the relationship between the nature reserve and rural areas.
