| The important exposition of "Lucid waters and lush mountains are invaluable assets." elevates sustainable development to a new level of green development The construction of ecological civilization is an important part of the cause of socialism with Chinese characteristics.It concerns the well-being of the people and the future of the nation.With the great attention and promotion of the Party Central Committee and the State Council,the construction of ecological civilization in China thas been achieved.Significant progress and positive results have been achieved.As the "lungs of the earth",forests play an irreplaceable role in the great cause of ecological civilization construction.Only the sustainable management of forests can maximize the beneficial effects of forests and add bricks and tiles to the construction of ecological civilization.The purpose of classifying forest working groups is to regularly monitor the management status and growth trends of each type in the same period,so as to take necessary working measures to guide the realization of sustainable forest management The classification of forest working groups is also an important link in the compilation of forest management plans,which affects the effect and level of forest management.Taking the non-commercial forest of Guangyun Forest Farm in Guangxi as the research object,using the forest land renewal data of Guangyun Forest Farm in 2016,this paper analyzed the current situation of forest resources in Guangyun Forest Farm,and carried out the organization of working groups of non-commercial forest,and the corresponding business measures.The main conclusions are as follows:(1)The general situation of forest resources and the structure of main factors of non-commercial forest in Guangyun Forest Farm were comprehensively analyzed.Based on the premise that the difference of forest management might be caused,four factors,tree species,forest origin,site type and management purpose(sub-forest species),were selected to classify the working groups of non-commercial forest.(2)The total area of non-commercial forest in Guangyun Forest Farm is 13189.8 hectares,which is divided into 1079 subcompartment through field investigation,including 10 tree species,10 site types,2 forest origins and 5 sub-Forest species.Firstly,ArcGIS 10.2.2 was used to extract the factor data of non-commercial forest outdoor subcompartment survey and to derive the map layer.Secondly,by using the data perspective table in Microsoft Office Excel 2010,the survey data of subcompartments were classified and statistically integrated layer by layer,the non-commercial forest of Guangyun Forest Farm was divided into 24 working groups.(3)On the basis of 24 optimized business types,the working measures of non-commercial forest in Guangyun Forest Farm are divided into 8 types:closure forest type,young forest tending type,replenishment type,management and protection type,tending and thinning type,special working group,selective cutting type and economic utilization type,and follow the principle of ecological priority,principle of operability,principle of matching and economic principle provide scientific,reasonable and effective types of working measures for each working group,forming a complete management technology system,so that specific working measures can be taken according to different working groups in future work and production.Through this study,a relatively complete classification system of working groups of non-commercial forests has been formed,and corresponding working measures have been designed in a more scientific way to make the forests develop in a healthier direction,so as to realize the sustainable utilization of forests,meet the increasing demand for forest resources,and serve the human ecology,it also helps to improve human ecology and social environment. |
