【摘要】 生物结皮既是沙漠地区最具特色的微自然景观,也是流动沙丘固定的标志,同时,在防风固沙、系统养分循环以及生态环境变化等方面扮演着重要的角色。2000年以后,我国的研究者紧密结合专业优势和地域特点,全方位地开展了生物结皮研究,并取得了明显的结果。本文从生物结皮的生物组成、结构与发育特性、物理化学特性和酶活性、生态作用、干扰的影响、生物结皮分布特征以及生物结皮人工接种固沙技术等方面论述了目前的研究现状,希望能够为今后的研究提供参考和借鉴。更多还原

【Abstract】 Biological soil crusts are a unique mini-nature landscape in desert district,as well as the obvious sign of fixing mobile dune.At the same time,biological soil crusts play an important role in fixing drift sand,nutrients circulation and ecological environment changes,and so on,respectively.Since 2000,the Chinese researchers began to make study on biological soil crusts from all sides,which closely combined with their majors and regions feature,and they obtained a lot of results.In this paper,we expound the study situation of biological soil crusts in China from the biological composition of biological soil crusts,structure and its development features,physicochemical properties and its enzyme active,ecological function,effects of disturbances,distribution characteristics and fixed technological of artifical inoculation algae,and so on,respectively.We hope this paper can offer some references and experiences for future study on biological soil crusts in desert district in China.更多还原
