The results showed that the plant community structure of tree layer in artificial restoration mode were much better than in natural restoration mode.
研究结果表明:人工恢复模式下乔木层群落结构要明显优于自然恢复模式;自然恢复模式下灌木层、草本层的物种数量、多样性指数略优于人工恢复模式,而植被盖度小于人工恢复模式;人工恢复模式下的土壤养分状况优于自然恢复模式。
2) artificial vegetation restoration
人工植被恢复
1.
In this study,soil physical and chemical characteristics in different develop stage after artificial vegetation restoration have been researched in Shazhuyu desert control site.
通过对青海省沙珠玉治沙站人工植被恢复不同土壤发育阶段土壤理化性状的研究,结果表明,人工植被恢复对荒漠化土壤具有很好的改善作用,随着流动沙丘被固定,机械组成中砂粒逐渐降低,粘粒和粉粒含量逐渐提高,土壤有机质和养分含量及CEC逐渐提高,土壤pH值变化不大,碳酸钙只是在表层升高。
3) artificial vegetation restoration

5) semi-nature rehabilitation
人工促进自然恢复
1.
The different measures of vegetation rehabilitation in subtropical degraded ecosystem, such as nature rehabilitation, semi-nature rehabilitation, and artificial rehabilitation, were compared, and the community comparison including species diversity, the niche, growth in diameter, volume of dominant trees, dry biomass of the communities and the soil nutrient substance were studied in this paper.
本项研究从比较生态学入手,分析了千岛湖地区退化森林生态系统不同植被恢复措施,即:自然恢复、人工促进自然恢复和人工恢复措施下的群落生态变化,比较了不同措施之间的生态响应差异,研究结果表明: ①在植被自然恢复过程中,由于生态系统退化程度的不同,存在草灌丛、灌丛、马尾松林、混交林和常绿阔叶林整个演替序列。

人工受精与人工授精
artificial fertilization and artificial insemination
我国学者把“人工受精”与“人工授精”两名词区别开来:前者指人工体外受精而言,后者指把精液注入到妇女的阴道或宫颈管、宫腔内,使精、卵在体内相遇。人卵体外受精与胚胎移植后出生的婴儿俗称试管婴儿。
