2.2 The planning method of ecological community uses ecological laws, aims at sustainable development, and is supported by engineering measures and technical means to plan and design the traditional community, so that the community can become a real ecological community and promote the sustainable development of the city with the ecological civilization of the community.
2.3 The content of ecological community planning Ecological planning should cover the natural ecological planning, economic ecological planning and social ecological planning of the community.
2.3. 1 natural ecological planning ① greening index: this index is one of the most important indicators to measure the level of ecological community construction. The green rate (including scenic spots and water surfaces) must reach more than 50%, and the per capita public green space is more than 28 square meters. Groundwater water conservation index: This index emphasizes the water seepage and water conservation ability of the building base, minimizes the concrete coverage area, and adopts natural drainage system to facilitate the infiltration of rainwater. The ideal index is that 80% of the exposed land in the community is permeable. ② Water-saving index: This index takes the development of alternative water resources (open source) and the use of water-saving appliances (throttling) as the main water-saving methods. The former refers to the design of introducing rainwater utilization or water purification system into residential building design, while the latter refers to the reuse of non-potable water and miscellaneous water that are not in contact with human body after rainwater and domestic sewage are collected and treated. ③ Energy-saving index: Pay attention to the design of energy-saving buildings, and save energy through air conditioning system, lighting, sunlight utilization and solar energy utilization. ④ Carbon dioxide and waste emission reduction index: This index encourages the application of light building structures, such as steel structures, and reduces the use of building materials such as sand, stones and bricks; Advocate simple home decoration design and recycling of building materials to save energy, resources, waste and carbon dioxide emissions. Sewage and garbage treatment indicators: The former needs to build a rainwater and domestic sewage diversion pipeline system, which is beneficial to the recycling of rainwater on the one hand and can reduce the sewage treatment capacity on the other. The latter refers to the classified collection of garbage and the recycling of resources. Green traffic index: low pollution, suitable for urban environment and healthy way to complete social and economic communication activities.
2.3.2 The overall goal of economic and ecological planning is to achieve high-speed economic growth with low resource consumption and light environmental pollution, and to develop civilized and scientific consumption patterns. Therefore, green consumption technology and green production technology should be applied to gradually change the energy structure, accelerate the substitution of renewable energy for fossil energy, and apply green energy such as hydropower, wind energy, bioenergy and solar energy; Adopt natural ventilation and natural lighting to reduce energy consumption; Promote green production and consumption in the community.
2.3.3 Social ecological planning establishes landmark buildings, central squares and attractive open spaces for residents to enhance the sense of belonging of the community; Establish ecological infrastructure with complete facilities and reasonable layout, and create a convenient living environment for people of all ages; The community provides diversified and personalized housing to ensure various economic incomes and the needs of people of all ages; The community has a central area where commercial activities, civic services, cultural activities and entertainment activities are concentrated.
