While paying attention to the pursuit of the economy, people are paying more and more attention to the pursuit of quality of life. China has vast territory and abundant resources, forest resources are particularly rich, in order to make full use of forest resources and regulate the use and protection of forests, China has promoted the development of forestry by deepening the construction and reform of state-owned forest farms, and using forest resources to obtain benefits to meet people's living needs. This paper explores the necessity and advantages of building a forest town by analyzing the reform and development situation of state-owned forest farms. 展开更多

【目的】综合评价湖北省金子山国有林场4种林分的空间结构,确定影响该区域林分结构的主要因素,为精准提升区域森林可持续经营水平和森林质量提供理论基础。【方法】基于常绿落叶阔叶混交天然林、杉木Cunninghamia lanceolata人工林、柳... 【目的】综合评价湖北省金子山国有林场4种林分的空间结构,确定影响该区域林分结构的主要因素,为精准提升区域森林可持续经营水平和森林质量提供理论基础。【方法】基于常绿落叶阔叶混交天然林、杉木Cunninghamia lanceolata人工林、柳杉Cryptomeria japonica var.sinensis人工林和鹅掌楸Liriodendron chinense人工林实测样地数据,选取角尺度、大小比数、混交度和密集度等林分空间结构指标,应用单位圆综合评价体系对4种典型林分进行综合评价。【结果】不同林分中随机木个体的占比均为最高,不同大小比数等级林木比例整体上接近。常绿落叶阔叶混交天然林中林木整体呈现随机分布(角尺度均值为0.492),林分混交良好(混交度均值为0.747),但优势不明显(大小比数均值为0.497),林冠连续覆盖(密集度均值为0.941),资源利用率高。其他人工林分也呈现随机分布(角尺度均值为0.505~0.514)或轻微聚集分布(角尺度为均值0.529)的趋势,混交程度均较低。有部分林木表现出一定优势,在杉木林中最为明显。3种人工林中鹅掌楸人工林林木处于很密集(密集度均值为0.768)的状态,而杉木(密集度均值为0.557)和柳杉(密集度均值为0.563)人工林林分处于较密集状态,林木还有一定生长空间。空间结构综合评价指数显示:常绿落叶阔叶混交天然林(0.600)林分状态优于杉木林(0.583)、柳杉林(0.521)和鹅掌楸林(0.487)。【结论】同一区域不同起源的林分结构存在差异,常绿落叶阔叶混交天然林的空间结构优于杉木、柳杉和鹅掌楸人工林。图2表6参37. 展开更多
