Research On The Planning And Design Of Country Parks With The Construction Of Rainwater Harvesting Green Space

Since the successful holding of the Central Urbanization Work Conference,the construction of the Sponge City has increasingly become an important way to solve the serious urban rain and rainfall-collecting greenbelt is widely used as one of the typical countermeasures;the emergence of country parks provides a more positive way to limit urban malformation and meet the natural needs of urban residents;after analyzing relevant theories and specific practices,some of the theories of the two can be effectively combined to guide the site planning and design,and achieve more efficient ecological services for the city.Based on the background of the times and goal-oriented,this paper studies the relationship between country parks and the rainwater harvesting green space;most of the existing researches have been found in most of the fields of rainwater harvesting green space and country parks,but they have not revealed the interrelationship between the two and the problem of building integration;therefore,this paper takes this as a starting point for research.Taking the Jinhu Country Park in Shijiazhuang City as an example,based on the based on rainwater harvesting green space and country parks,in response to the special land status within the site,through land suitability analysis and watershed analysis under the GIS platform,the land suitability and the scope of the catchment area in the area where the site is located are derived,and the collected rainfall is further calculated;in this way,the water design and landscape modeling of the country parks are guided,and a reasonable and scientifically based rainwater harvesting country park planning and design is made.Based on the above results,in combination with the method of questionnaire,the data of tourists’ intention to rural activities are obtained the functional layout of the site is guided and the demand of tourists is combined with the rainwater harvesting green space to form a countryside activity space with rainwater-harvesting characteristics,so that tourists can experience the unique countryside parks and enhance the attractiveness of the park.After the park is planned and designed,the SWMM model is used to simulate the rainwater to verify the end flow of the park design under the intensity of each recurring storm,and to conclude whether the site meets the requirement of rainwater absorption so as to verify the rainwater harvesting efficiency of the site.The construction of the rainwater harvesting country park and the organic integration of the two provide a more versatile way of thinking and solutions for us to build country parks and alleviate urban water resources,promote the improvement of the urban stormwater management system,to supplement the ecological functions of country parks..The construction of rainwater harvesting country parks will become an efficient measure to contribute to the urban sponge system and provide a valuable reference for the future ecological construction of country parks.
