围栏封育，干扰源消除，群落逐渐由不稳定的一年生植被向次稳定的灌丛化植被和相对

The steppe landscape is dominant but not apparent in its patch and area, and the percentage of the original vegetation of Stipa bungeana steppe is very low in the study area, which is apparently characterized by human disturbance. The diversity and evenness of patches in the study area are higher than those of the steppe landscape area, and the fragmentation and the isolation of the steppe are the highest. The landscape shapes of artificial arbor woods and cultivated lands are the simplest, and the landscape shapes of classical steppe and artificial shrub are in an instable stage.

结果表明：(1)草原景观在其斑块数和面积上虽然仍居首要地位，但其优势并不十分明显，而且该区原生植被本氏针茅草原只占很小的比重，呈现出非常明显的人类干扰特征；(2)研究区斑块的多样性程度和均匀度较高，而面积的多样性程度和均匀度较低，同时，典型草原的景观破碎度最大，景观分离度也最大；(3)景观形态上，人工乔木林和耕地的景观形态最为简单，典型草原和人工灌丛这2种景观类型还处于很不稳定的阶段。

Shield tunneling is one of the excavation methods. Compared withother excavation methods, it has many advantages, such as good self-stability and less disturbance to the ground.
