Gaofeng Forest Farm Of Precious Tree Species Planning Base Cultivati On Research On Display

Precious tree refers to the production of lumber and wood products for precious, rare tree species, with high economic value, long growth cycle, high environmental requirements, etc. Precious tree species of large-scale artificial cultivation to protect biodiversity, promote the development of forestry industry, forestry sustainable development is of great significance.Based on peak forest farm pond two breakout quartel911land44.6hm2as the research object, the peak forest on construction within the scope of the precious tree species breeding base planning and design research. This study USES the principle of operational research base for the overall planning and layout, planning and transportation road construction, screening survey concluded that planting trees and configuration scheme, and carry on comprehensive analysis and evaluation, planning scheme is put forward. The results show that:(1) Multi-objective land use planning by using the principle of operational research, set up land use planning model, put forward the general layout scheme of different, through the objective function and constraint condition calculation, it is concluded that precious tree species breeding area, greening of local tree species cultivation area, popular science exhibits the best area of seedlings and distribution solutions.(2) According to road function, economy, comfort, convenience, safety, environmental protection and so on investigation and analysis, planning and design of road structure, traffic entrance, car parks, recreational facilities, production management, tourism demand.(3) In this paper, through the investigation and analysis of Guangxi valuable tree species and afforestation of native tree species growth situation, put forward to want to follow the appropriate tree, functional, economic principles, selection of suitable planting rare tree species and afforestation of native tree species, and obtain the best scheme.(4) Comprehensive analysis and evaluation results show that the planning and design of the method proposed in the paper, to promote the development of rare species and biodiversity protection, provide theoretical basis and scientific reference for the state-owned forest farm of rare species breeding base construction.
