| With the rapid development of social economy, people's life is getting better and better, landscape construction has become an important way to improve the quality of life, more green is required. Landscape plant conservation as an important part of the landscaping gets more and more attention, so it's very important to raise the major problems of landscape plant conservation and found out the solution through the analysis of them. Now landscape designing, construction and conservation have a close relationship in theory. Conservation should be given more attention, this is getting more people's recognition. But in fact, the three links severe disjointed. For the weak current situation of landscape plant conservation, this paper started from the significance of landscape plant conservation, raised several major problems, and found out the solution through the analysis of the problems. Through the thought of the problems of landscape plant conservation and how to solve them, we can get the following conclusion:1.There are many factors which influence landscape plant conservation. The natural factors, such as climate, scourge, wild animals destruction, etc. Human unable to control these factors, also can't prevent them from harm of human society. Man-made factors, including social factors, technological factors, the factors caused by the problems in the process of design, construction, conservation. Human can't avoid natural disasters, but only just repair the plant damage after the disaster. For the negative impact caused by man-made factors, human beings can avoid them by control the behavior of themselves.2. The seriously disjointed relationship of design, construction and conservation is the main problem in landscape plant conservation of our country at present. Landscape plant conservation is the weak link in maintenance industry in this country. Landscape designing, construction and conservation have a close relationship in theory, but in fact, the three links severe disjointed. At present, domestic landscape plant conservation cost about 20-25 percent of landscape construction cost, but actually landscape plant conservation investment accounts for only 10-15% of landscape construction. Starting from the relationship of the three links, according to investigation and field research, propose the main problems of the botanical landscape plant conservation, Use science theory to analyzes the problems and puts forward solutions.3. Pay attention to three aspects to avoid maintenance problems caused by designing:(1) Prevent blind reference. (2) Insist on humanized design, promot the development of landscape construction.(3) Improve the personnel level of designer, to make plants to achieve the best growth state and ornamental effect.4. Pay attention to four aspects to avoid conservation problems caused by construction: (1) Pay attention to the cooperation between construction personnel, according to construction procedures construction strictly, supervise construction steps strictly by specialized organization. (2) Strengthen the quality checks of construction material, to ensure the materials quality qualified. (3) Correctly handle the construction rubbish. (4) Improve the personnel level of constructor, correctly operate construction equipment, avoid to cause the plants to hurt.5. Solve the six questions in the process of maintenance: (1) The capital investment of maintenance comparatively less. By strengthen the importance of conservation to improve maintenance the status in landscape construction, and then drive injection of capital. (2) Strengthen the unit of the tripartite company or the connection of design, construction and conservation. (3) Specific operation maintenance should adjust season changing constantly. (4) The dosage of increased not be free of pesticides. (5) Improve the personnel level of conservator.All in all, only landscape plant conservation get enough attention, the problems of conservation can obtain the effective solution, make conservation system to get perfect, and promote the development of the overall landscape construction industry. |
