摘要
以瓮安县朱家山国有林场为调查对象,采用实地调查、遥感技术与GIS技术获取林场森林资源相关信息。结果表明:瓮安县朱家山国有林场的主要树种为栲树、马尾松、杉木,占比分别为30.41%、3.95%、3.38%;楠竹、樟树和梾木的健康度、郁闭度相对较高,林区健康状况良好;栲树、马尾松、杉木健康度和郁闭度相对较低,覆盖度相对高;楠竹、樟树和梾木的林下幼苗和幼树数量相对较多,栲树、马尾松和杉木林下幼苗和幼树数量相对较少;楠竹、樟树和梾木乔木层、灌木层和草本层的植被物种数量总数分别是33种、29种、31种,栲树、马尾松、杉木的植被物种总数分别是24种、26种、28种。瓮安县朱家山国有林场拥有丰富的树种资源,但部分树种的健康度、覆盖度相对较差,林下天然更新不足,林地植被群落结构相对单一。提出应根据实际情况,从建立病虫害预警机制、加强土壤管理、开展多样化种植、长期监测适时调整等方面进行生态修复。
In order to understand the current situation of forest protection in Zhujiashan State-Owned Forest Farm in Weng'an County,Guizhou province,field investigation,remote sensing and GIS were used to obtain forest and resource information.The results showed that the main tree species in Zhujiashan State-Owned Forest Farm were Castanopsis fargesii Franch,Pinus massoniana Lamb.and Cunninghamia lanceolata,accounting for 30.41%,3.95%and 3.38%.The health and canopy of Phyllostachys edulis,Cinnamonmum camphora and Cornus macrophylla Wall.were relatively high,and the health of forest area was good.The health and canopy of Castanopsis fargesii Franch,Pinus massoniana Lamb.and Cunninghamia lanceolata were relatively low,and the coverage was relatively high.The number of seedlings and saplings under Phyllostachys eduli,Cinnamonmum camphora and Cornus macrophylla Wall.was relatively large,while the number of seedlings and saplings under Castanopsis fargesii Franch,Pinus massoniana Lamb.and Cunninghamia lanceolata was relatively small.The total number of vegetation species of Phyllostachys eduli,Cinnamonmum camphora and Cornus macrophylla Wall.in arbor layer,shrub layer and herb layer is 33,29 and 31,respectively.The total number of vegetation species of Castanopsis fargesii Franch,Pinus massoniana Lamb.and Cunninghamia lanceolata is 24,26 and 28,respectively.It can be seen that the Zhujiashan State-Owned Forest Farm in Weng'an County has rich tree species resources,but the health and coverage of some tree species are relatively poor.The natural regeneration under the forest is insufficient,and the forest vegetation community structure is relatively simple.It is urgent to carry out ecological restoration according to the actual situation from the establishment of disease and pest early warning mechanism,strengthening soil management,diversified planting,long-term monitoring and timely adjustment.
