Spatial Management And Plan Of Non-commercial Forest In Culai Mountain Forest Farm

The non-commercial forest is the bond to achieve the unity between environment anddevelopment; it not only satisfies requirements in material products and environment servicesof human survival and development, but also plays an important role in maintaining globalecological balance and conserving biodiversity. To give full play to these effects ofnon-commercial forest, scientific management is crucial. In this paper, we mainly focus on thenon-commercial forest in Culai mountain of Shandong province. On the basis of the forestresource inventory data in2010, first of all,51management types were classified in virtue ofMicrosoft Office Excel and SPSS; then, the possibility of occurrence of forest pests and firewas exposited by the analysis of spatial pattern and composition in forest resource spatialdistribution maps which were made by CAD. Finally, relevant management measures wereproposed for defects of different management types. The results would provide the basis forforest sustainable management.The main research contents and results were summarized as follows:(1) Related data acquired from non-commercial sub-compartments in Culai mountain ofShandong province were arranged and analyzed to figure out the characteristics of thenon-commercial forests in the area: forest category was single, and its structure was irrational;it had poor ability to resist pests and fire because of more pure forest and less mixed forest;age structure was irrational and concentrated; forest quality was low because of simple standstructure and biodiversity; non-commercial forest was mainly distributed in mountain; it hadpoor forest ecosystem structure and function because of low biomass per unit area andproductivity.(2) On the basis of the forest resource inventory data, in virtue of Microsoft Office Exceland SPSS, combining with the classification principles of non-commercial forest,51management types were classified based on origin of the forest, tree species in the forest, sitetype and management target.(3) Combining with the forest resource inventory data, tree species, origin, canopydensity, age and site type spatial distribution maps of non-commercial forest in Culaimountain were made by CAD. On the basis of the above, the possibility of occurrence ofmajor forest pests was explored by the analysis of spatial pattern and composition of forestresource. The results showed that: a large area of forest pests easily occurred innon-commercial forest of Culai mountain because of pure forest which was mostly composedby single species; moreover, forest pests easily occurred in the stand that had low canopy density, or was in a gentle slope, as well as in the stage of young forest and over-mature forest.Therefore, on the basis of the possibility of occurrence of major forest pests in differentmanagement types, relevant management measures were proposed for the management typeswhich had poor ability to defense major forest pests.(4) Combining with the forest resource inventory data, tree species, origin, canopydensity and age spatial distribution maps of the stands on both sides of firebreak were madeby CAD. On the basis of the above, the combustibility of the stands on both sides of firebreakwas explored by the analysis of spatial pattern and composition. The results showed that: thestands on both sides of firebreak in Culai mountain were mostly composed by artificialconiferous forest which had highly combustibility; moreover, part of the stands had lowcanopy density, or was in the highly combustibility stage of young forest and over-matureforest. Therefore, relevant management measures of the stands on both sides of firebreak wereproposed according to the fireproof defects of different management types.
