This paper reviewed the research situation and history on the forest restoration burned blanks and summed up the research methods used into four scales: seed-bank scale, community scale, ecosystem scale and landscape scale. The new technologies such as GIS & Remote Sensing used to vegetation restoration were also summarized. The strategies and developing trend of vegetation restoration research on burned blanks were discussed.展开更多

The catastrophic forest fire that occurred in Daxing抋n Mountains on May 6, 1987 devastated more than 1.33?06 hm2 of natural forests, which leaded to the formation of some mosaic areas with different burn intensities. Two forest farms of Tuqiang Forest Bureau (124?5-122?8E, 53?4-52?5N) were chosen as a typical area to analyze the post-fire landscape change by drawing and comparing the two digital forest stand maps of 1987 and 2000. The landscape lands of forest were classi-fied into 12 types: coniferous forest, broadleaf forest, needle-broadleaf mixed forest, shrub, nursery, harvested area, burned blanks, agricultural land, swamp, water, built-up, grass. The results showed that: 1) The burned blanks was almost restored, some of them mainly converted into broadleaf forest land during the process of natural restoration, and coniferous forest land by the artificial re-forestation, and the others almost changed into swamp or grass land; 2) The proportion of forest area increased from 47.6% in 1987 to 81.3% in 2002. Therefore, a few management countermeasures, such as the enhancing peoples consciousness of fire-proofing and constructing species diversity, were put forward for forest sustainable development.展开更多

文摘针对商业合版印刷无法适应满版成品离线自动分离设备的要求,探索并提出一种能实现满版成品离线自动分离的拼版方法。根据满版成品离线自动分离设备的工作原理,给出成品自动分离要求,然后依据成品自动分离要求,利用Adobe Illustrator和TongYin PDF Expert软件完成产品拼版。实例分析结果表明,相较于人工成品分离,所实现的满版成品离线分离提升了近2倍的工作效率,同时也减少了2/3的人员需求;相较于拆标机,满版成品离线自动分离设备的生产效率提高了1倍,且换版时间不超过5 min。此方法为实现商业合版印刷成品的自动分离提供了新的解决方案,带来显著的效率提升和成本降低。
