Biodiversity is one of the front areas of current biological research. The mechanisms of the formation, spatial distribution pattern, conservation and utilization of biodiversity have been an important area of biological and environmental research. In this study, through analyses of data about plant diversity, animal diversity, geographic factors, climatic factors, and energy factors by use of GIS software, statistic software and ecology software, the mainland of China was divided into 241 small districts of 2° by 2°. The environmental factors in each district were analyzed and isopleth maps of environmental elements were depicted.
生物多样性是当今生物学研究的热点问题之一,生物多样性的形成机制和分布格局以及保护利用问题一直是生物学和环境科学所研究的重要内容,本文由此出发,以中国陆地为研究区域,通过植物多样性数据、动物多样性数据、地理因子、气候因子、能量因子等资料,利用MAPGIS、MAPINFO等GIS软件,SPSS、DPS等统计学软件以及CANOCO等生态学软件,将中国陆地划分为241个小区,分析了各区内的环境特点,统计了各区内生物多样性的数量,并绘出环境因子等值线图,中国陆地种子植物科、属、种,裸子植物种、蕨类植物种、兽类、鸟类、爬行类、两栖类种数的等值线分布图,对中国陆地植物、动物多样性现状、分布格局及与环境因子的关系进行了研究。

In the dissertation, the theory and application of monitoring the habitat of Locusta migratoria manilensis Meyen were studied on the basis of reviewing the present research on the fields of locust habitat, the theories and methods to monitor its change, and the related technologies. Processed MODIS, ETM+, ground and aerial survey data were used to monitor the habitat of Locusta migratoria manilensis Meyen in the Baiyangdian Lake. As a result, the method and process were brought forward to monitor the habitat of Locusta migratoria manilensis Meyen in the Baiyangdian Lake.
本文在综述以往对生境、蝗虫、监测和预警等的研究和运用的相关技术基础上,分析了东亚飞蝗的发生、发展与其生存环境的关系,提出了东亚飞蝗生境监测的理论;并以白洋淀蝗区为例,开展了运用多源数据(MODIS、ETM+、航摄数据和实地调查资料等)融合方法对东亚飞蝗生境进行监测的应用研究;最后,提出了白洋淀东亚飞蝗生境监测的模式。

Information is stored in mass storage systems in large units called files. A typical file may consist of a complete text document, a photograph, a program, or a collection of data about the employees in a company. The physical properties of mass storage devices dictate that these files be stored and retrieved in multiple byte units. For example, each sector on a magnetic disk must be manipulated as one continuous string of bits. A block of data conforming to the physical characteristics of a storage device is called a physical record. Thus , a file stored in mass storage will typically consist of many physical records.
在大容量存储系统中,信息是以称为文件的大的单位储存的,一个典型的文件可以是一个全文本的资料,一张照片或一组关于公司员工的数据,大容量存储系统的物理特性表明,这些文件是按照许多字节为单位存储的检索的,例如,磁盘上每个扇区必须作为一个连续的二进制位串进行操作,符合存储系统物理特性的数据块称为物理记录,因此存放在大容量存储系统中的文件通常包含许多物理记录。
