So studying the processes and mechanisms of soil hydrology of microbiotic crusts as well as analyzing its influence on soil water conditions in fixed dunes will play an important role theoretically and practically in understanding the evolution of artificial vegetation community in fixed dunes and the security of artificial sand-fixing vegetation system.

因此，通过野外试验揭示微生物结皮对土壤水文过程的影响和机理，评估其对雨养植被固沙区土壤水环境的影响，对于认识固沙区人工植被群落的演替和人工植被固沙体系的安全性都有着重要的理论意义和实践意义。

Special staining methods, such as Masson and the Van Gieson staining were used to study the distribution of collogen fibers and elastic fibers. ResultsBy HE staining, the subepithelial connective tissues and vessels in the pterygium were more prominent than normal conjunctival tissues. An amorphous subepithelial superficial hyalinized zone and coarse eosinophilic granular materials were observed in the pterygia, but they were not found in normal conjunctival specimens. Coarse fibers were visible only in the deeper subepithelial connective tissues of pterygial samples. With Masson′s staining, the dense staining of collagen fibers was also more prominent in the pterygium than in the subepithelial connective tissues of normal conjunctiva. Abnormal collagen fibers were visible in the deeper sub-epithelial connective tissues of pterygial samples. With Van Gieson staining, abnormal collagen fibers were visible in the deeper subepithelial connective tissues. Dark coarse elastic fibers were found in the abnormal fibers only in the subepithelial deep connective tissues of pinguecula in the pterygia but not in the conjunctiva. With immunohistochemistry staining, MMP-3 was strong in the pterygial epithelium, moderate in fibroblast and absent from pterygial vascular walls. LN was strongly expressed in the blood vessel wall, moderately in the epithelial basement membrane and absent from the entire stroma.
