【摘要】：生物土壤結(jié)皮在干旱、半干旱地區(qū)分布較為廣泛,約占陸地總面積的40%,生物土壤結(jié)皮是支撐該區(qū)生態(tài)系統(tǒng)主要的生物表面特征,在改善生態(tài)環(huán)境和草地土壤養(yǎng)分調(diào)控方面起著重要作用。自1960年以來(lái),國(guó)內(nèi)外許多學(xué)者對(duì)其生態(tài)功能進(jìn)行了大量研究,但對(duì)生物土壤結(jié)皮演替機(jī)制及其微生境土壤養(yǎng)分變異特征的研究尚不明確。為此,本文就國(guó)內(nèi)外該領(lǐng)域近50年來(lái)的研究進(jìn)展和成果進(jìn)行了詳細(xì)闡述,以期了解生物土壤結(jié)皮發(fā)育對(duì)土壤肥力的作用過(guò)程;同時(shí),也為研究干旱半干旱區(qū)退化草地生態(tài)系統(tǒng)的恢復(fù)與重建提供一定的科學(xué)思路。
[Abstract]:Biological soil crusts in arid and semi arid area is widely distributed, accounting for about 40% of the total land area, biological soil crusts are supporting biological surface characteristics of ecosystem mainly in this area, plays an important role in improving the ecological environment and soil nutrient regulation. Since 1960, many domestic and foreign scholars have made a lot of research on the ecological function, but the research on crust succession mechanism and microhabitat variation of soil nutrient characteristics of biological soil is not clear. Therefore, the domestic and foreign research progress and achievements in the past 50 years in this field in detail, in order to understand the development process of biological soil crusts on soil fertility; at the same time, also provide some scientific ideas of restoration and reconstruction of degraded grassland ecosystem of arid and semi arid areas.
