Study On Forest Health Assessment And Management Counter Measures Of The Dawei Mountain National Forest Park

In this paper we base on the statements of the evaluation on the forest in the world and take the second survey results of Liuyang forest resource in 2013 as a data source. By using the some methods, such as analytic hierarchy process, Fuzzy comprehensive method and combining the soft wares of ArcMap10.0、Matla、SPSS, we process and analysis the date. Based on the result, we obtain the healthy class of the forest resource of the Dawei Mountain National Forest Park and put forward the management countermeasures of forest resources under different health condition.Thus, we are able to provide a theoretical basis and reference for the further resource management and sustainable utilization of the Dawei Mountain National Forest Park. The main results are the following.(1)The resource feather of the Dawei Mountain National Forest Park:the forest area of the Dawei Mountain National Forest Park is big, the forest cover rate is very high, the protection of the forest vegetable is will. The landscape classes of the Dawei Mountain is rich, the classes of the used land is complicated. The order of the squares of the dominant tree species is:Shrubs Group> Chinese Fir> bamboo> Mason pine> broad group.(2)The construction of the evaluation system and the confirmation of the weight:by combining the survey results and the self-feathers of the Dawei Mountain National Forest Park we choose the appropriate constraints at last and using the Analytic Hierarchy Process we confirm the appropriate weights. The first index contains the four feathers,Community integrity, continued stability, the vitality of the system and the recreation of the landscape. The weight are 0.1213,0.4203,0.2685 and 0.1899, respectively. The second index contains eight feathers,community structure, canopy density, naturalness, stand origin, the ages of the group, the amount of every hectare, plaque density and the degree of aggregation. The rate are 0.0303,0.0910,0.1401,0.2802,0.0895,0.1790,0.0950 and 0.0949,respectively.(3)The small classes of the Dawei Mountain National Forest Park are in the Sub-health state level. Among them, the number of the healthy small classes is 84 (16.77%), the square is 708.8546hm2 (20.53%); The the number of the sub-healthy small classes is 230 (45.91%), the square is 1793.0689hm2 (51.94%); The subsub-healthy small classes is 160 (31.94%), the square is 808.6034hm2(23.42%); The unhealthy small classes is 27 (5.39%), the square is 141.7623hm2 (4.11%). The order of the squares of the every healthy small class is sub-health small class> subsub-healthy small class> healthy small class>unhealthy small class. The main part of the healthy class is shrub, while the Chinese fir is the main part of the subsub-healthy small class and unhealthy small class and the bamboo and shrub are the main part of the sub-healthy small class. The Mason pine and Chinese fir are in the subsub-healthy class. The broad group, Chinese fir and shrub are in sub-healthy. Among the healthy classes, the proportion of the nearly mature forest is 48.53%, among the sub-healthy classes, the proportion of the mature forest is 40.46%, while in unhealthy class, the proportion of the medium age forest is 56.42%.(4)The dominant tree species of the healthy class is shrub, the main purpose of this part should be child care; The distribution of the subsub-healthy small class is dispersion, it is affected by human factors relatively largely,the main purpose of this part should be management.The dominant tree species of the subsub-healthy class is Chinese fir, the main purpose of this part should be foster with intermittently harvester,replanting other kinds of colored broadleaf.The main part of unhealthy small class is artificial planting young trees, so we should take the measures of dynamic monitoring and reforming the technology management every two months, half year and one year on this small class.
