| The forestland is the important forest and national strategic resource. Moreover, it is also the most basic material of all forest resources and forest development, which is significant to forestland’s protection and utilization plans, to ensure homeland security and promote the continuing development of forestland, as well as defend and improve the forest eco-efficiency, and social economic benefits. The major conflicts of our country in forestland are more people possess less woodland area and the general quality of woodland is not good enough to satisfy the social economic development. The forestland conservation and utilization researches are carried out based on these conflicts. In this paper, the author takes Debao country for example, reviewing the present research of forest protection and utilization to study the main content of forest protection and utilization. The specific content is as follows:The author analyze the present protection and utilization of woodland in Debao, and the result states that the forest resource obviously have regional distribution; differences in the structure; the layout of Arbor species in the county are the fir, the loose pony tail, star anise, and other broadleaf trees and other native species; the origin of the forest is plantation. Compared with1999, this county’s forest area has significantly increased; forest cover and green rate also has raised; substantial growth in all types of forests and forest reserves; forest quality has improved greatly.The author takes Cluster analysis and GIS control to carry out the function sections. The results are supposed to inspect and amend to strengthen the scientific of the woodland section. There are four function sections of forest resource in Debao:The central and southern is medicinal and economic forest functional areas; western area is water conservation forest and rocky desertification control; northeast is water conservation forest and economic forest functional area; the last one is Mt.Huanglian functional areas of biodiversity.This paper fist apply the BP neural network model to predict the forestland occupation in Debao county in the coming two years. Instant of Complex manual analysis and forecasting, this model provide an easy way to protect the forestland occupation. The results state like that the Levy occupation of forest land area in Debao is136.244hectares and145.652hectares in2011and2012.The author according to the actual situation of Debao County built a scientific and rational forest land quality grade indicator system, using the analytic hierarchy process and buffer woodlands traffic location to classify the quality grade of forest land. Woodland quality classification results in De bao show that:the first grade is19.2hectares, the second31,730, the third87,992.4hectares, the forth75324.2hectares, and the fifth23hectares.The author gives the key project planning of forestland in De Bao, the main focus of the works will include no stumpage forest land greening projects, ecological public welfare forest construction projects, nature reserve construction projects, urban and rural green construction projects, rocky desertification control projects, industrial raw material forest construction projects, Characteristic economic forest projects and forest tourism construction projects... |
