| In recent years,the planning and design of rural landscapes under karst landforms has been affected by natural and human factors,which have led to a significant increase in planning difficulty.In order to study the strategic methods of Gaopo Miao Township planning in Guizhou Province,this article analyzes the remote sensing of the township in 2019.Data,with the help of field surveys,interview records,"source-sink" landscape pattern analysis,AHP analytic hierarchy method and other research methods,the human landscape pattern and ecological landscape pattern of Gaopo Miao Nationality Township are obtained,and the rural landscape is comprehensively analyzed in Arc GIS software.Layout planning strategy,select Shimen Village as the pilot for specific planning and design.the result shows:(1)In the ecological landscape pattern of Gaopo Miao Nationality Township,the high-security pattern space accounts for 48.61% of the area of the study area,and the original natural form is protected in this area;the medium-security pattern accounts for 17.82%,and a reasonable rural ecological system should be constructed.Ensure the stability of the ecosystem;low-safety space and construction areas account for 33.57%,which can be restored and developed based on ecological value.Lands with low ecological value can guide the development of tourism and living construction land.In the cultural landscape pattern of Gaopo Miao Nationality Township,the high-security pattern space accounts for 44.08% of the area,and the spatial texture and landscape structure of the site should be maintained in this area;the medium-security pattern accounts for 32.23%,and the long-term historical evolution of the area should be deepened.The cultural characteristics of ethnic minorities;low humanities and safety patterns and construction areas accounted for 23.69%,green tourism service facilities can be added,and modern tourism,service industry,agriculture,and processing industry systems can be developed.(2)The study of the rural landscape pattern of Gaopo Miao Township shows that most of the core protection areas of the township are concentrated in the Kaxia area,which is related to the peak forest and peak cluster landforms in Kaxia,and the slope of Kaxia is relatively large,which is not conducive to the large slope.The development of large-scale human settlement activities.The core area of the rural landscape in Kashang area is scattered,and the whole is distributed in linear and scattered points,and its ecological and cultural functions are relatively fragile.(3)In Kashang Village,46.66% of Shimen Village,23.75% of Dahong Village,and 66.27% of Bailong Village are humanities core and ecological construction areas,and ecological protection forests are established around them.30.19% of Dirao Village is a humanistic core and ecological construction space,and 19.89% of Xin’an Village is a humanistic core and ecological intermediate space.The ecological core area is reserved for diffusion space in the north and south.42.86% of Jieshang Village is a humanistic core and ecological construction space,and ecological space is reserved in the southeast.24.97% of Pingzhai Village and 30.07% of Yunding Village are the core of humanity and ecological construction,forming the tourism core of Jiugaopo Village in Kashang area,and also an important ecological protection area.35.93%of Gaopo Village has a dual-core pattern of humanity and ecology,which connects the tourism corridors of various villages and connects the ecological network of other villages to build an ecological corridor network.37.23% of Shuitang Village is the ecological core and humanistic construction space,and the ecological corridor core on the card is constructed.The "acupuncture" method is used to construct the humanistic landscape node without interfering with the operation of the ecosystem.In Kaxia Village,21.35% of Shanping Village is an ecological core and humanistic intermediate space,and “acupuncture and moxibustion”places the tourist space to form a linear corridor.22.33% of Wuzhai Village is the ecological core and humanistic construction space,which connects the Kashang and Kaxia areas,and the southern center is planned for a tourist area.42.50% of Pilin Village is a dual core space of humanity and ecology,which is a hub of ecological and human landscape.The central area of the market town can be set at the junction of Pilin Village and Wuzhai Village.The ecological core and humanistic construction area of Dongkou Village account for 36.34%,and an ecological conservation area is established in the south.24.31% of Zhangji Village is the ecological core and humanistic construction space.The tourist resources in the east are dotted and distributed,and tourist corridors are established.More than 50% of Keli Village,Longyun Village,Jiading Village,and Gaozhai Village are mainly ecological protection.The linear human landscape corridors are connected in series to create mysterious exploration and forest health and maintenance spaces,and large-area ecological conservation areas are built.Maintain the stable and sustainable development of the ecosystem.(4)In the study of the rural landscape pattern of Shimen Village,a pilot project in Gaopo Miao Township,master plan design and ecological landscape design(planning and designing of shelterbelts,planning and design of wildlife crossing passages,plant configuration design and skyline planning and design)were made.With humanistic landscape design(house building design,road space design,sewage discharge system design,landscape node design,sign design),the overall humanistic core is the main line,the development of the main line of tourism,"acupuncture-style" interspersed with homestays,farmhouses,and trade markets A series of tourism products,such as restaurants,enhance the attractiveness of the population and enhance the interaction between people and land.Connect the ecological core space in the surrounding space of the humanistic core,plant ecological shelter forests to protect the original natural landscape,optimize housing construction,road space,drainage system and leisure nodes,carry forward the characteristic culture of the Miao nationality,and enhance the rural landscape of Shimen Village. |
