Research On Development Of Precious Color Healthy Forest In Tiantai County

The construction of precious colored healthy forests is of great significance for promoting the healthy and stable development of forest systems,optimizing ecological functions,beautifying landscape structures,enhancing urban taste,promoting forest tourism,and achieving social,economic and ecological sustainable development.And it is also the core of major decisions the Central Committee of the Communist Party of China and the Zhejiang Provincial Committee and the Provincial Government made on forest tending and forest quality improvement.The construction of precious colored healthy forests includes three aspects:the construction of precious timber species breeding bases,the construction of colored forests,and the construction of healthy forests.The content of these three aspects should be scientifically coordinated and adapted to local conditions.The content of these three aspects should be scientifically coordinated and adapted to local conditions.Priority is given to the development of colored forests around main arteries,important tourist routes and scenic spots.Places with good site conditions will give priority to the development of precious tree species according to the principle of appropriate tree-fitting.All forests need to build healthy forest ecosystems based on ecological principlesThe methods of constructing precious colored healthy forests proposed in this paper are based on the actual situation of Tiantai County and implemented in combination with the project.According to their respective characteristics,the following specific construction methods are proposed.First,for the construction of precious timber species breeding bases,the cultivation of precious tree species by means of afforestation,replanting and transformation,etc.,for different areas,using "thinning plus replanting","land preparation plus afforestation" as allocation method,and "precious tree species plus fast-growing tree species" as selection method.They are both used to create a base for the formation of precious tree species.Secondly,the method of "the theme tree species plus key tree species" are proposed for the colored forests construction to select tree species,and different structural allocation modes and afforestation measures are adopted for different regions.Third,for the construction of healthy forests Areas where pine wood nematode has been harmed,updated by cutting pine trees,cultivating or cultivating other tree species;in the relatively safe area,do a good job of prevention and control,in the important areas,measures such as moderate thinning and sub-plant replanting are adopted to improve the disease resistance of forestsTwo innovative construction methods were proposed in the study(1)Colored creative forests construction.Create font graphics in the place where the site conditions are suitable,combined with the construction of colored forests,in mountains(2)Colored forests construction for water conservation.Around the reservoir,planting water-resistant tree species in the range between the lowest water level and the highest water level,combined with the construction of colored forests,further enhance the ecological environment and forest landscape around the reservoir,and at the same time play a certain role in water conservation.Through economic benefit analysis,social benefit analysis,ecological benefit analysis and landscape benefit analysis,it is concluded that the construction of precious colored forests has high practical value for the local forest landscape reconstruction of Tiantai.At the same time,natural conditions,mountain tourism and forestry construction in Tiantai County are Zhejiang Province is highly representative,so it has a good reference value in a considerable range.Put forward the law of universality for the construction of precious colored healthy forests.
