389-415.)。
In particular, the skinning formed by cyanobacteria and mosses, due to secreting sticky polysaccharide protection knot in cell peripheral
Film (sheaths), facilitates in conjunction with soil particle in coagulating soil.In addition, the root of lichens and mosses and soil grain
Son combines, and improves soil to the erosion resistance of wind and water.
Recently, the parties concerned are studied, it is intended to promote Biological Soil Crusts (BSCs) using mosses and cyanobacteria
It is formed, during the final ecological system degradation shortened after environment is destroyed.As its concrete example, Chen et al. (Chen,
L.Z.et al., 2006, Journal of Arid.Environments 67,521-527.) disclose a kind of technology, Xiang Zhong
Micro- sheath algae (Microcoleus is inoculated on the sand dune of the reduction in the state Inner Mongol (Inner mongolia, China)
Vaginatus), the artificial algae conjunctiva in desert is formed；Wang et al. (Wang, W.B., et al., 2009, Soil Biology
And Biochenmistry 41,926-929.) a kind of technology is disclosed, in desert area, straw checkerboard barrier (straw is set
Checkborard) and Self-watering is to irrigate (automatic sprinkling micro-irrigation) system, Xiang Qi
It is inoculated with cyanobacteria rehabilitating soil；Xiao et al. (Xiao, B., et al., 2011, Applied Soil Ecology, 48,11-
17.) open, the loess plateau (loess plateau) of Xiang Zhongguo is inoculated with the Biological Soil Crusts formed by mosses (moss), into
Pedestrian's work proliferation results, the proliferation of Biological Soil Crusts permeated, rainwash (overland flow), run-off
(runoff) and the influence of water re-supplied.In addition, Malam Issa et al. (Malam Issa, O., et al., 2007,

Biomass of the leading document to the cyanobacteria being inoculated in artificial bio-membrane's soil crust (BSCs) forming process is stated, is effectively cultivated
Method etc., is not still stated clearly, in terms of area in large scale forms artificial bio-membrane's soil crust (BSCs), there is also
The problem of cultivating a large amount of cyanobacterias.
Existing desert or just in the area of desertification, in order in the Zinc fractions Biological Soil Crusts of such kind of area
(BSCs), a kind of straw checkerboard barrier system (straw checkerboard system) for being inoculated with the microorganisms such as cyanobacteria is developed.
The method, which had in the short time, stabilizes the sand dune of adverse environment condition, effectively puts aside the organic matter and nutritional ingredient of soil
The advantages of (Li, X.R., et al., 2006, Ecological Engineering, 28,149-157.).But the straw checkerboard barrier system
System is not only difficult to be formed uniformly Biological Soil Crusts, but also it is long to form the time, then 2~3 years short, it is long then 5~7 years.And this
The also non-mechanization of method then needs many manpowers if applicable in sweeping area, repairs certain above scale and destroys soil
When, there is very big expense burden.
For this purpose, related research attempt to develop it is a kind of with the effect while be economically applicable to extensive area
Method, while the microorganism that can form Biological Soil Crusts is fixed on sand bed surface at the beginning, with moisture or nutrition at
The soil fixing agent that point aspect can promote microorganism growth is handled, repair ecological environment (Liu, J., et al., 2012,

and Physics,203,1526-1531.；Yang,J.,et al.,2007,Environmental Pollution,149,
125-130.).The soil fixing agent improves the stability of sand, prevents because of wind or rainfall, desert or just in the dry of desertification
It is mobile that dry and regional partial desiccation sand is detached from barren land.When using the soil fixing agent, with without using the case where compared with,
The intensity of the Biological Soil Crusts formed in barren land, moisture storage capacity etc. are improved in the future, it is easier to barren
Ground soil restoration of the ecosystem.But the soil fixing agent is by sad fungi or the Biodegradable substance structure of bacterial decomposition
At, and while being exposed to intensive ultraviolet and the violent temperature difference, decomposes, and soil stabilization function gradually dies down, and comes from long-term angle
It sees low efficiency, the biomass to form the microorganism of Biological Soil Crusts can be reduced, there are problems.
And it is let out by oil storages facilities such as extensive oil storage setting, petroleum pipeline, gas stations through the oils between several years or even many decades
Leak cause contaminated soil, or by coal mine cinder contaminated soil and waste coal mine soil due to moisture it is very insufficient, cause
Plant stops growing, the also secondary pollutions such as initiation underground water pollution.
The environmental hazard that the soil ecosystem and human body caused with soil pollution is subjected to is of increasing concern, U.S. etc.
Developed country in exploitation, be applicable in restorative procedure and physics, chemical repair method biologically.But these methods, by causing
The reason of soil pollution, the scope of application are limited, and repair certain scale more than soil when, expense burden it is quite big.
