In this paper,through the investigation of Jixi County,Anhui Province state-owned Zhen tou forest farm of every subcompartment factor,evaluation index system of forest ecological function,using the state forest administratuion of Jixi county Zhen tou forest farm of each small forest ecological function evaluation,based on,using of relevant methods of landscape ecology,landscape pattern of ecological function of Zhen tou forest farm were analyzed,combined with current situation of the development of forestry,and gives some suggestions to the state-owned tou Zhen tou forest farm in the future development and forest management.Results show that:From the point of view of ecological function,Jixi County state-owned Zhen tou forest farm ecological function for secondary forest constitutes the whole forest landscape background,it plays a decisive role in the forest ecological function of the strength,led to forest overall ecological function index only for 0.416,ecological function of the lower-middle;The forests with good ecological function are few and scattered,lack of scale ecological effects,on the whole ecological function of forest play a lack of influence.So in the future need to by raising the level of forest management,improve the quality of forest,improve the ecological benefits of forest,and gradually make the ecological function of forest as a background for the forest landscape,to make a full used of the scale ecological effects.The forest ecological function not only with its structure,the community structure of tree species and the growth and development status of the forest,but also with the artificial operation intensity.Broad-leaved forest and coniferous and broad-leaved mixed forest of high ecological function,so in the forest should as far as possible the use of native broad-leaved tree species for planting or replanting;unreasonable anthropogenic interference will of forest ecological function exert a great influence,and therefore need to change the past mode of operation is given priority to with final felling,as far as possible,using the selective cutting and shelterwood cutting mode of operation,reduce the interference of human factors on forest,give full play to the ecological functions of forests.The state-owned forest farm is an important force for ecological restoration and economic construction of our country,is the most important infrastructure to safeguard the national ecological security,but for a long time,the state-owned forest farm unclear function,management system,operating mechanism,the sustainable development offorestry is facing severe challenges,the state-owned forest farm of Zhen tou existing forest ecological function is not high.So according to the change of our country's forestry situation and trend of reform of state-owned forest,Zhen tou forrst farm should be in accordance with the opinions and demands of national,provincial and county on the reform of state-owned forest farm,actively promote the reform,innovation of forestry management system,fully mobilize the enthusiasm of all aspects of afforestation,reforestation,forest protection,improve forest quality,enhance forest ecological function to forestry development strategy of ecological construction,promote forestry development mode dominated by timber production to ecological restoration and Construction of the main,by the use of forest to obtain economic benefits to the protection of forest to provide ecological services based model for the maintenance of national ecological security,the construction of ecological civilization and the beautiful China to make greater contributions.Clearcutting-the traditional mode of operation has great influence on the renewal of forest ecological function,but this is decided by the nature of the past state forest timber production,due to the current state-owned forest farm properties have been changed,so the forest management can be used near natural forest management,the target tree management method,the specific approach is the first calibration target tree cultivation,harvesting trees provide space for the purpose of tree growth,stand in the forest is broken,sapling breeding of native tree species in the forest by replanting broad-leaved species or improve the quality of the forest,and then in the stands have the option of cutting part meet the demand of large size class to obtain the target tree large diameter wood,and then added back in pary of thr target tree,then cutting,in this way,on the one hand can obtain the required large diameter timber and precious materials,on the other hand due to adopt the way of selective felling,and natural regeneration,reduce the disturbance to the forest,to maintain the balance of the forest ecosystem,so that the forest can fully and stably play the ecological function of the forest.
