Study On Mangagement Type Classification Of Ecological Forest In Xinfeng County

In recent years, our country pay more and more attention to the construction of ecological forest, facing of the huge demand for ecological environment, Improve the quality of ecological forest become the operation of the problem to be solved, and the division of the ecological forest management type is the premise of scientific management. The research object of this paper is the ecological forest of Xinfeng county,and it’s based on the forest management, using a comprehensive method of combining theory with practice, field investigation with scientific reasoning, determined the guiding ideology,principles, methods of nomenclaturing the type name, and on the basis of division the ecological forest management type, proposed the management target and measures of ecological forest.The main conclusions are as follows.(1)The results on the study of the forest management show that:the main age group composition of the ecological forest are the young and the middle-aged forest, the percent of the young forest is54.29%in arbor, the middle-aged forest is42.32%, the near-mature forest is3.39%; the pure stand is76.37%,the mixed stand is23.63%; the canopy density above0.7is37.10%, the canopy density between0.40to0.69is52.66%, the canopy density between0.20to0.39is10.25%, the main distribution of community structure is relatively complete. As a whole, the quality of the ecological forest is low.(2)Choose management purpose, tree specices group, origin and the grades of the soil fertility to dvision the ecological forest management type of Xinfeng county, and divsioned fourteen forest management types.(3)On the basic of analysis the community structure, tree species composition, management goa1of all management types, proposing the development goal and making corresponding management measures of the fourteen types.
