　　Citizens wonder:

　　If a good tree is digging, then dig it and see it as a waste

　　The reporter searched and found that in recent years, many cities have fought for "a tree" or "a pot of flowers".

Past reports show that people's reasons for questioning are mostly "don't understand": "A good tree is dug up when it is said to be dug, and then a new tree is replaced, which is a waste."

　　Ms. Wang, who is committed to the protection of animals and plants, said that she had reported to the relevant department in a certain place that there were indiscriminate felling of old trees, but the reply from the other party was that the trees were necrotic and needed to be replaced. "But I went to the scene to see , those trees that were cut down by the middle are all good, and there is no damage at all."

　　Ms. Wang also said that she has found that in some cities, plants and flowers are frequently replaced, "Summer is one kind of flower, winter is another kind, and even sometimes, in order to create a festive atmosphere, large-scale replacements are specially made. I don't know where the flowers that were exchanged went or how to deal with them."

　　Ms. Xu, a citizen of a certain place who has reported relevant issues, told reporters that some of the replaced green plants were growing well, and with the company of time, the citizens have become accustomed to them, and the unreasonable replacement is difficult for everyone to accept, " What we hope is that the relevant departments will carry out scientific planning and not waste human and financial resources on useless work, and in the case of having to replace them, they will be able to inform you in detail the relevant reasons."

　　an expert:

　　There are many reasons for the replacement of urban green plants

　　An industry insider engaged in garden design told reporters that it is normal for herbal flowers to be replaced frequently, after all, herbal flowers have a short growth cycle.

The woody trees and shrubs in the city are generally not replaced every year. If they are replaced, it may also involve the reasons that they have to be replaced. For example, the planted trees are not suitable for the local climate and soil, and their growth conditions are not good. Others need to be replaced. type.

Or some trees have not survived after transplanting, suffered diseases, man-made damage, etc., and need to be replanted. "Also, the trees have affected the construction of the road (including cables and pipes under the road), so they need to be transplanted elsewhere first, and then replanted with other trees. Plants, etc."

　　The reporter found that some cities responded to the problem of green plant replacement.

For example, the city of Enshi, Hubei has stated that the replaced street trees are basically of the "old, weak, sick and disabled" category. Replacing street trees is not to dig up and replant good street trees, but to replant only the places where there are missing plants. Replacing trees that are infested, severely damaged, or apparently unviable.

　　Wuzhou City, Guangxi Province once stated that the reason for "replacing kapok with kapok" is because the beautiful kapok has high requirements on soil, does not grow for many years, does not bloom, and has more thorns; on the other hand, 4 After the lane was changed to 6 lanes and the sidewalk was narrowed, it was "not on the same line" as the roadside trees in the adjacent road section.

　　The aforementioned industry insiders told reporters that, in his opinion, with the advancement of urban construction, there are more and more connections between people and green plants. Therefore, when doing a good job in urban landscaping, it is necessary to listen to experts' opinions and have a For public participation, it is necessary to comprehensively consider urban construction and development, capital investment, and whether it meets the requirements of urban greening planning.

　　Experts claim:

　　Urban green space planning needs to take into account historical factors

　　Xu Bin, an associate professor at the School of Landscape Architecture and Architecture of Zhejiang A&F University, told reporters that there is a professional judgment on whether trees are necrotic. It may appear that there is no serious problem on the outside, but in fact, growth problems have occurred.

"Generally speaking, the planning and construction of urban gardens are strictly economical, and it is definitely inappropriate to 'replace flowers and plants before they wither' or 'replace old trees for no reason'. It is not ruled out that there are very few This situation occurs, but it cannot be generalized.”

　　Xu Bin said that the frequent replacement of herbs and flowers similar to what Ms. Wang mentioned is mostly caused by the changing seasons of flowers and plants. For example, urban flowers generally change four, five, and six times a year. High requirements for landscaping.

"Green plants such as flowers and plants have their own growth cycles, including perennials, annuals or seasonal." Xu Bin said that from the perspective of saving, all cities currently advocate the use of perennial or woody flowers and plants. " In this way, there is no need to replace frequently, only proper care is required, such as sorting litter, controlling pests and diseases, fertilizing fertile soil, etc.”

　　In Xu Bin's view, urban green space planning is a system and a sub-item planning of the overall urban planning, which must meet or comply with the overall urban planning.

When planning a green space, it is necessary to take into account historical factors, including the "past, present and future" of this place, that is, what the past of this green space was like, whether there are allusions and stories, what is the current situation, and its efficacy How, the satisfaction of the people, whether it needs to be adjusted according to other urban planning in the future, "Therefore, the planning and construction of urban green space landscape should be 'according to local conditions, forming a system, highlighting characteristics, and doing what we can'."
