At present, the local governments have further promoted the comprehensive rectification of rural environment, and related engineering projects are fully rolled out.When investigating the establishment of ecological civilization demonstrations, the author found that many places used small and micro -living realms such as ponds, ditches, pit ponds, rivers, seasonal ponds, and depressions in front of the houses and fields.Plant a little local aquatic plant, and build some small wetlands or ecological safety buffers to further purify water quality, regulate water storage sources, and protect biodiversity, which plays an unexpected governance effect.
Compared with measures such as the construction of rural sewage treatment plants, small and micro -living realms such as small rivers, streams, and ponds in front of farmers do not require great investment and can also improve the ecological environment.Especially in the water village of Jiangsu, many rural areas have brought together a large number of river channels, breeding ponds, etc. These natural evolution formed, which has the characteristics of high dispersion rate, large water and soil contact surface, obvious climate adjustment effects, etc., which can effectively reduce surface runoffs.Provide more suitable habitats for creatures.Make full use of these small and widely distributed small and micro -living borders. For improving the rural ecological environment, it can also achieve more effort.
First of all, let these small rivers and small ponds return the ecology as soon as possible.At present, small and micro -living realms distributed in front of the house and the fields are degraded or even disappeared in various development activities.In the process of land arrangement, rural rejuvenation, and development of rural tourism, we must combine ecological restoration and transformation of the ponds and ditches in the villages in combination with the construction of beautiful rural areas, retreating farmland and wetness, river governance, and black odor water governance.By designing small and micro -living realms with different sizes, different depths, maintaining the terrain of the original life realm, not destroying the original river, shore, and 埂, try to use local tree species to prevent the rivers and rivers hardening, and with water level adjustment to ensure the water system systemUnblocked, retain rural ecological bases, and improve biodiversity.
Secondly, the restoration of small and micro -life realm should be based on natural solutions.Adhere to the principles of protecting priority and natural recovery, make full use of natural degradation and recovery capabilities, and minimize artificial intervention as much as possible.Basically retain the original terrain, restore the original ditch into seasonal dry and humid ditch, allow the water system to connect, build a near natural plant community, expand the ecological environment capacity, reduce the cost of pollution, and effectively protect the natural ecological endowment.
Third, we must guide the improvement of small and micro -living conditions according to local conditions.Unlike large -scale protection areas such as nature reserves and wetlands, these small units cannot prepare unified technical specifications, and these small and micro -life areas are often closer to people and difficult to cut points to protect and repair people’s production and life.In view of this, some policy or funding support can be given for future management and maintenance.If it can be combined with other functions such as leisure and entertainment, the cost of manual management and maintenance in the later period can be lower.
