With the change of seasons, many cities renew seasonal flowers and plants to make the city scenery better. However, there are also some cities that blindly introduce exotic flowers and plants and precious trees, which consumes a lot of costs in daily maintenance. Some are pursuing visual effects, thinking that precious flowers have larger flowers, more colorful colors, and more interesting points, and it is easier to do a good job in the surface of urban greening; Some are pursuing the title of "Garden City", eager to create "Internet celebrity landscape" and "traffic highland", and establish a new "business card" for urban development; Some of them substitute their own feelings for the feelings of the masses, ignoring the ...... of the actual natural conditions in the locality
The National Conference on Ecological and Environmental Protection held not long ago made it clear that efforts should be made to improve the diversity, stability and sustainability of ecosystems, increase the protection of ecosystems, and effectively strengthen the supervision of ecological protection and restoration, so as to leave a beautiful ecological space for future generations.
In recent years, all localities have attached great importance to ecological environmental protection, and ecological restoration and ecological construction projects have been increasing day by day. However, there is also a phenomenon of excessive greening and ecological formalism in some places, and some cities are "greedy for foreigners", thinking that they can "afforestation in one day" and "scenery in one night"; Some cities blindly follow the trend and plant "Internet celebrity" trees, simply seeking differences and innovations; In some places, in the name of urban greening, they are engaged in "image projects" and "government performance projects" ......What do you think about this?
First, the overall evaluation.
The original intention of promoting the construction of urban greening is to plant greenery for the people, benefit the masses, and create a beautiful home where man and nature coexist in harmony. However, at present, there are formalist problems such as following each other's trend, greedy for beauty and seeking foreign goods, and eager for quick success, which we should be vigilant and correct, and urban greening should adhere to local conditions and scientific planning.
2. Hazards. 1.endanger the stability of the city's original natural ecosystem. The non-localization, homogenization of species, and simplification of structure of greening seedlings will reduce the species richness and naturalness of urban ecosystems, weaken biodiversity, and be prone to large-scale pests and diseases. At the same time, the blind introduction of alien plants will also increase the risk of alien species invasion.
2.It affects the health of urban residents. The pollen and fly floc of some flowers and trees are important allergens that affect human health and can easily lead to human health risks. For example, "pollen allergy" has become an epidemic for many urban residents.
3.Increase the cost of management and maintenance, resulting in extravagance and waste. Violating the laws of nature and engaging in "formalism" of urban greening construction not only requires the urban garden department to invest a lot of long-term management and maintenance costs, but also causes serious greening waste due to poor planting effect.
3. Reasons. 1.Some cities lack patience in promoting greening construction and excessively pursue "green achievements".
2.There are defects in the working mechanism of urban greening, and there is a lack of scientific guidance.
Fourth, countermeasures. 1.Follow the ecological law and adhere to the "people-oriented" concept of urban greening. In the process of promoting urban greening, local governments should strengthen the learning and understanding of the construction of ecological civilization, and explore the road of ecological environmental protection guided by ecological priority and green development.
2.Improve the working mechanism of urban greening and do a good job of scientific assessment. Experienced professionals should be invited to do a good job in project design and environmental assessment, make full use of regional biodiversity resources, take into account the short-term and long-term, and formulate a scientific and reasonable professional plan for urban greening construction system.
3.Strengthen the supervision and discipline accountability of urban greening construction. Efforts should be made to discover and correct the formalism problems in the process of urban greening, unblock the channels of social supervision, and if we encounter excessive innovation and beauty, resulting in ecological damage, and the masses have a strong reaction, we should reflect on it in a timely manner, and take it seriously, and standardize the construction and operation and maintenance management of urban greening.
