DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The present invention provides three technical solutions, including the following embodiments: Example 1: Please refer to Figure 1 A rural small watershed regional planning method specifically includes the following steps: S1. Data collection and collation: Collect basic information on the topography, water system distribution, transportation conditions, and industrial resources of the small watershed, and integrate them; S2. Type classification: Based on the multi-dimensional standards of area scale, mountainous terrain, river network morphology and location conditions, small watersheds are classified into types. According to the area scale of the small watershed, each rural small watershed is divided into first-level small watersheds, second-level small watersheds and third-level small watersheds. Small watersheds of different levels have differences in resource endowment and development potential, and different planning strategies are required. First-level small watersheds are rich in resources and have great development space, so they can be planned as large-scale cultural and tourism complexes, such as creating water parks and lakeside resort hotel clusters in combination with wide water areas, and supporting high-end homestay villages. The second-level small watershed focuses on medium-sized characteristic industrial parks, such as the concentrated development of organic fruit and vegetable picking gardens and flower planting and exhibition bases, which drive the surrounding farmers to plant orders and increase their income steadily; the third-level small watershed focuses on boutique niche projects, such as using small flat land in the mountains to build handmade pottery workshops and folk food experience courtyards to attract self-driving tourists and backpackers to travel in depth, and activate the economy with small but fine business formats. According to the mountainous terrain classification, the small watershed is divided into low mountain and hilly small watersheds (below 800 meters above sea level, with a relative height difference of 100 to 300 meters), Semi-alpine small watersheds (800 to 1200 meters above sea level, with a relative height difference of 400 meters) and plateau small watersheds (above 1200 meters above sea level, with a relative height difference of 500 to 1000 meters). Small watersheds with different terrains have different characteristics in terms of ecological environment and tourism resources, and need to be planned according to local conditions; cycling greenways and outdoor expansion camps are opened in the gentle slopes of low mountain and hilly small watersheds, connecting the surrounding farmhouses to extend the tourists' stay time; semi-alpine small watersheds take advantage of the cool climate to develop summer health and wellness homestays, and plant high mountain tea, Chinese medicinal materials and other high-quality food. Value-added crops and supporting processing plants allow agricultural products to be added value locally; plateau-type small watersheds create extreme sports bases, such as cliff jumping and alpine rappelling projects, and develop special festivals in combination with folk customs to stimulate consumption and increase income from cultural industries through tourism. According to the morphological structure of the river network in the small watershed, the small watershed is divided into "I"-shaped small watersheds, "Y"-shaped small watersheds, feather-shaped small watersheds, branch-shaped small watersheds and mixed small watersheds. Small watersheds with different morphological structures have different advantages in water resource utilization, landscape construction, etc., and need to be planned in accordance with actual conditions. "I" In "Y"-shaped small watersheds, linear waterfront commercial streets are arranged along the water flow to display and sell local specialties and handicrafts; in "Y"-shaped small watersheds, tourist distribution centers are set up at the forks to divert tourists to different themed villages, such as the Fishery Culture Village and the Farming Experience Village; in feather-shaped small watersheds, decentralized eco-lodges are built at the ends of the feather-shaped water system, and water bamboo raft tours are organized to connect various points; in branch-shaped small watersheds, charming water towns are built around the main river channel, and kayaking competitions and night light show boat tours are introduced in the branch river channels; mixed small watersheds integrate the characteristics of various water systems and create hot spring resorts, wetland bird watching parks, and canyon exploration areas in different areas to achieve diversified tourism integration;According to the location conditions, small watersheds are divided into location-advantage small watersheds, location-guided small watersheds and location-restricted small watersheds. Location-advantage small watersheds are at a relatively good level in terms of industrial resources, geographical location, transportation conditions, infrastructure conditions, etc., and are suitable for the development of high-end tourism; location-guided small watersheds have outstanding advantages in one or several location factors, and need to be guided to give full play to their advantages and promote the development of tourism; location-restricted small watersheds are at a lagging level in all aspects and need to increase investment, improve infrastructure, and enhance the level of tourism development. Location-advantage small watersheds attract international and domestic Well-known tourism brands will establish presence in these areas, jointly develop high-end customized tour routes, and cultivate local high-end tourism service talent, such as international tour guides and sommeliers, to enhance the added value of the industry. Location-driven small watersheds will highlight their locational factors. If they are close to large cities, they will focus on weekend family trips and study tours, improve supporting transportation routes and study bases, and stimulate the suburban leisure economy. Location-restricted small watersheds will strive for policy support and focus on improving key infrastructure, such as first building external trunk roads and then gradually introducing appropriate light-asset tourism projects, such as tent camping sites and sketching and creation bases, to leverage initial development with low investment. S3. Settlement characteristics analysis: From the perspective of the relationship between water systems and human settlements, the settlement type characteristics of small watersheds were analyzed, including beaded water system-settlement structure, parallel linear water system-settlement structure and scattered water system-settlement structure. The three-life function synergy analysis was carried out based on the three indicators of cultivated land productivity (tons / hectare), public service facility density (units / km²) and forest coverage rate (%). First, the original data were normalized by range, and cultivated land productivity and facility density were used. , forest coverage rate is ; Then the indicator weights are calculated by the entropy weight method, specifically by calculating the entropy value of each indicator , and then according to the weight Determine the contribution of each indicator; ultimately build a synergy model Villages with a D value < 0.6 were identified as weak areas of synergy. During implementation, measurements of Village A in a small watershed on a Minjiang River tributary revealed a cultivated land productivity of 7.2 tons / hectare, a facility density of 0.6 units / km², and a forest coverage rate of 58%. The calculated weights w1 = 0.35 (cultivated land), w2 = 0.45 (facilities), and w3 = 0.20 (forest), resulted in a synergy degree D of 0.57, identifying it as a weak area. Based on this, a new health service station was planned at the coordinates E118°15'30" and N26°42'15" to enhance its ecological function. A beaded water system-settlement structure refers to the distribution of settlements along a water system in a string-like pattern. This type of settlement structure typically occurs in small watersheds shaped like a "I" or "Y." The water system serves as the primary link between settlements, promoting communication and interaction between them. When planning, we can make full use of water resources to create water town tourism landscapes and enhance tourism appeal. In addition to creating water town tourism landscapes, we can also layout traditional fishing experience points, water curtain movie squares, etc. along the water systems between settlements, increase night entertainment projects, and stimulate catering and accommodation consumption; organize water markets to allow farmers to directly sell agricultural products and homemade souvenirs, reducing intermediaries; encourage residents to transform their houses into houseboat homestays and water restaurants; settlement structures usually appear in feather-shaped or branch-shaped small watersheds. The water system provides settlements with rich water resources and ecological landscapes. When planning, we can focus on protecting the ecological environment of the water system, creating green tourism routes, and improving the quality of tourism. While protecting the water system ecology, we can build bicycle lanes along the route, connect the ecological farms and orchards of each settlement, and launch cycling and picking package tours; the houses in the settlement should be uniformly planned in appearance and transformed into pastoral-style holiday homes, with supporting cultural spaces such as rural libraries and handicraft workshops and classrooms to improve the quality of tourism and attract mid- to high-end tourists, driving housing prices. Rental and service income increased; a water resource protection cooperative was established to allow residents to participate in water system monitoring and ecological restoration work and receive labor remuneration, balancing ecology and livelihoods. A scattered water system-settlement structure refers to settlements scattered around multiple water systems. This settlement structure usually occurs in mixed small watersheds. The water systems are relatively scattered, but relatively independent settlements have been formed around each water system. When planning, we can make full use of the characteristic resources of each water system to create diversified tourist landscapes to meet the needs of different tourists. Differentiated tourist landscapes can be created around each independent water system, such as building a folk museum to display local history and culture, developing a river tracing adventure route, and operating an outdoor barbecue campsite. Joint marketing between settlements is encouraged, and a "small watershed exploration passport" is launched. Tourists can redeem gifts by checking in at different settlement feature points to promote mobile consumption in the entire region. Support residents to develop decentralized e-commerce service points, use centralized logistics distribution to sell specialty agricultural products and handicrafts, and solve the sales problem of remote settlements. S4. Development of industrial development strategies: Develop targeted industrial development strategies based on the development stage and unique resources of the small watershed, including strengthening infrastructure construction, developing eco-tourism, and increasing the added value of agricultural products. Specifically, agricultural innovation: subdivide planting and breeding areas based on the soil and climate of the small watershed, grow high-quality rice and raise freshwater fish and shrimp on low-altitude flat plains, grow specialty fruits and keep bees on the hillsides, and grow cold-resistant medicinal herbs and graze sheep in the mountains; introduce smart agricultural technologies, build small weather stations and soil sensor networks, accurately guide production, and reduce disaster losses; establish a traceability system for agricultural products, affix "originating from the small watershed" labels, enhance market recognition and price competitiveness, and combine with tourism to launch diversified products such as farming experiences and customized gift boxes for agricultural products.

[0020] Forestry value-added: On the basis of ecological forest protection, economic forest belts are planned, fast-growing and high-yield forests are planted for timber processing, special trees such as red maple and ginkgo are used to create autumn viewing forests, forest economy is developed, mushrooms are planted, and poultry is raised; forest products are deeply processed into handicrafts and health care products, such as peach wood carvings and pine pollen capsules; forest trails and tree house B&Bs are opened between forest areas, allowing the forestry industry to shift from selling timber alone to increasing income in multiple dimensions through ecology, tourism, and processing.

[0021] Fishery upgrades: Improve traditional fish ponds into ecological recycling aquaculture ponds, introduce a fish-vegetable symbiotic model, purify water quality and increase vegetable production; create fishery theme parks that integrate ornamental fish farming, fishing competitions, and fishing cuisine experiences; develop specialty fish products, such as air-dried fish and fish sauce, and sell them throughout the country through tourist souvenir shops and e-commerce platforms, extending the fishery industry chain and driving fishermen to transform from fishing to breeding, processing, and services.

[0022] Diversified tourism expansion: Integrate tourism resources within the basin to design four-season themed tours featuring "flower viewing in spring, summer escape, fruit picking in autumn, and health and wellness in winter." Develop study tour courses centered around topics such as geological science, folklore heritage, and ecological protection to attract school groups. Cultivate rural tourism maker teams to create cultural and creative products themed around small watersheds, such as picture books, notebooks, and folk music. Organize various festivals and events, such as mountain marathons, folk culture festivals, and agricultural product harvest festivals, to continuously fuel tourism and convert tourist traffic into increased wealth for residents. S5. Planning report generation and output: Based on the above analysis results and strategic recommendations, a complete planning report is generated, planning drawings are drawn, and implementation recommendations are put forward.
