Forest resources variation along with the main rivers in typical forest region of Changbai Mountain

The restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology. Through interpreting the images of Remote Sensing in 1985 and 1999, the basic information of forest resources of Lushuhe Forest Bureau, which is a typical forest area of Chanbai Mountain was obtained with support of GIS. By dividing Land covers of Lushuihe area into 10 types (water body, residential land, stump land, farming land, wetland, mature conifer forest, midlife conifer forest, mature broadleaf forest, midlife broadleaf forest, and man-made young forest) and dividing the riparian zone into four buffers (in turn 1000, 2000, 3000, 4000 m away from the river), the changes of riparian forest resources during 1985–1999 were analyzed. The results showed that the deforestation intension has obviously decreased and the whole environment has been evidently improved, but the riparian ecosystem was still flimsy. In buffer 1, 2, 3 the area of midlife conifer forest increased largely, but the areas of other types of land covers all decreased. Midlife conifer forest had a comparatively good status in the three buffers. In buffer 4, midlife conifer forest, mature conifer forest, and mature broadleaf forest formed a forest-age rank that is helpful to stabilize the forest ecosystem and exert its functions. Area percentage of wetland decreased in buffer 1, buffer 2, and buffer 3, even in buffer 4 in which forest ecosystem rehabilitated comparatively well, so protecting and rehabilitating wetland is a very difficult task.

杀螟·噻嗪酮乳油防治松褐天牛的研究

To control Monochamus alternatus and its amount of population is one of the effective ways on controlling Bursaphelechus xylophilus.The Japanese black pine which were badly harmed by M.alternatus were sprayed with the ditution from diluting fenitrothion · buprofezen 50%EC with water to 100 times, 200 times and 300 times. In this trial, the treatment is divided into two groups: one is of the different concentration but the same object (trees in the forest), the other is of the same concentration but different environmental condition (trees in the forest and felling trees indoor). Each treatment repeated five times. In the meantime, the check is not treated. After twice trial, the result indicated that the mortality rate of M. alternatus is 71.33%, 52.31% and 37.82% in the condition that trees in the forest were sprayed with the 100 times, 200 times and 300 times fenitrothion·buprofezen, and 69 69% in the condition that the felling trees indoor were spraded with 100 times fenitrothion·buprofezen, but the mortality rate of the check is only 8.92%. By this trial, it was also found that the dead adults of M.alternatus laid in the entrance of emergance hole, so enhancing the somatic character of fenitrothion · buprofezen can enhance the injury ratio of larva and pupae of M.alternatus.

竹盲走螨、胡瓜钝绥螨对毛竹害螨的控制作用研究

应用实验种群生命表数据分析毛竹林本土优势种竹盲走螨和引进种胡瓜钝绥螨对毛竹4种害螨南京裂爪螨、竹裂爪螨、竹缺爪螨、竹刺瘿螨的控制能力。结果表明①胡瓜钝绥螨取食上述4种害螨的世代存活率分别为90．4％、77．55％、87．93％、81．63％，每雌总产卵量分别为38．12粒、45．77粒、35．59粒、30．26粒，而乡土优势种竹盲走螨取食上述4种害螨的世代存活率分别为95．23％、100％、87．7％、80．48％，每雌总产卵量分别为44．5、46．8、41．15、20．1粒；②竹盲走螨以南京裂爪螨为猎物时其内禀增长率(0．155)与引进种胡瓜钝绥螨(0．154)相近，均明显高于南京裂爪螨(0．1089)；③竹盲走螨以竹裂爪螨为猎物其内禀增长率(0．152)与胡瓜钝绥螨(0．152)相同但明显低于竹裂爪螨(0．192)；④竹盲走螨以竹缺爪螨为猎物时其内禀增长率为(0．148)明显低于引进种胡瓜钝绥螨(0．175)和其猎物(0．185)；⑤竹盲走螨取食竹刺瘿螨易大量逃跑，雌螨产卵量低，引进种胡瓜钝绥螨取食竹刺瘿螨能正常生长发育，但是其内禀增长率(0．144)明显低于其取食上述其余3种害螨的内禀增长率，产卵量高于当地种竹盲走螨，并描述1998年以来每年5—6月助迁人工繁殖的胡瓜钝绥螨控制毛竹害螨蔓延的效果。
