点击Run按钮时，选定的栅格将输出到系统临时目录，于是产生一个参数列表，Fragstats执行，然后生成的文件 frag_av.class，frag_av.land和frag_av.full。这些临时的文本文件将被删除补丁电网与未来的执行，因此，如果你想保 留原来的Fragstats输出，重命名文件是必要的。 When Run is clicked, the selected grid is exported to the system temporary directory, whereupon a parameter list is generated, Fragstats is executed, and then the files frag_av.class, frag_av.land, and frag_av.full are generated. These temporary text files are removed with the next execution of Patch Grid, therefore renaming the files is necessary if you wish to keep the original Fragstats output.
从这些统计数据读入ArcGIS中，并在用户指定的位置（如果输出表的名称和位置都没有指定，分析将无法运行）表中。根据被用来运行栅格 （网
格）图层的大小和计算机的速度，它可能需要几分钟时间，用户得到一个消息，说输出已成功创建。输出表将无法显示，直到收到这个确认消息。 Statistics from these are read into ArcGIS, and presented in a table in the location specified by the user (analysis will not run if an output table name and location are not specified). Depending on the speed of the computer being used to run Patch Grid and the size of the raster (grid) layer (theme) being analyzed, it may take a few minutes before the user gets a message saying that the output was created successfully. The output table will not be available for viewing until after this confirmation message is received. 以下是栅格数据空间统计的详细参数：
The following is a breakdown of the \Statistics for Grids\dialog box, one section at a time: 图层 Layers
这个图层窗口（左上角），ArcMap图层列表中的数据会显示为可选择。图层菜单中的每一个图层都可以作为分析数据。但每运行一次只能分析一个图层。选择需分析的图层。
In the Layers panel (top left), the layer(s) (theme) selected from ArcMap's table of contents will appear. Each layer (theme) that is present in the Layers menu can be analyzed; however, only one layer (theme) can be analyzed at a time. Select the layer (theme) that you wish to analyze. 类型 Class
类型框属性从选定图层的属性表中选择。
The Class box allows selection of the class field from the selected layer's attribute table to be analyzed. Both character and numeric classes can be analyzed. 分析 Analyze by
该参数用于选择在景观还是类型尺度上的统计计算。如图层需进行景观层面的分析，将对无论属于哪种类型的斑块或者单个值的数据都进行统计并生成报告。相反，在类型层面的分析时，统计结果只报告景观中每种类型的情况。
The Analyze By option allows calculation of spatial statistics at either the Landscape or Class level. If the layer (theme) is being analyzed at the landscape level, all patches, regardless of the class they belong to, will be analyzed and a single value will be reported for each statistic. In contrast, if the layer (theme) is analyzed at the class level, the statistics will be reported for each class within the landscape. 输出表格名称 Output Table Name
输出表的名称是输出表的名称（和驱动器的路径），将创建一个包含空间统计。如果该表已经存在，附加/覆盖选项将变为可用。默认是追加。 Output Table Name is the name (and drive path) of the output table that will be created containing the spatial statistics. If the table already exists, the Append/Overwrite options become available. The default is Append. 综合统计
General Statistics
栅格板块分析提供了6大类统计项：
There are six categories of statistics available in the Patch Grid Analyst:
8. Area面积
9. Patch Density and Size Metrics 斑块密度和大小 10.Edge Metrics边缘 11.Shape Metrics形状
12.Diversity Metrics多样性 13.Core Area Metrics核心区
只需选择要计算的，并在空间统计输出表中报告的统计数据。选择\选择所有\选择所有的统计信息，或选择\选择\无\，以明确的选择。某些统计数字只适用于在景观水平。同样，某些统计数字只适用多边形层（主题）。对于统计的适用性（多边形或栅格）和缩写可参见统计摘要（附注1）。
Simply select the statistics to be calculated and reported in the spatial statistics output table. Choose \All\to select all the statistics or choose \Certain statistics are only applicable at the landscape level. Similarly, certain statistics are only applicable on polygon layers (themes). For a listing of statistic applicability (polygon or raster) and abbreviations refer to Statistic Summary.
Core Area核心区
只适用于栅格数据的空间统计对话框中的核心区度量。当要求对矢量图层进行核心区分析时，用户必须首先从patch 菜单建立核心区（创建一个核心区图层），然后把它当作一个正常的斑块图层的进行分析。从空间统计的对话中选择所需的统计项（即，平均斑块大小，等等），结 果将是核心区的统计数据。在创建核心区层（主题）时会有两个字段添加到图层的属性表：I）的核心区面积 和II）斑块面积。然后可以确定选择适当的位置来对核心区图层进行统计分析。
Core Area Metrics from the spatial statistics dialog are only available for raster (grid) layers (themes). When core area
statistics are required for vector layers (themes), the user must first Create Core Areas (create a core area layer (theme)) from the Patch menu and then treat the core area layer (theme) as a normal patch layer (theme). Choose the desired statistics (i.e., Mean Patch size, etc.) from the spatial statistics dialogue and the result will be core area statistics. When creating core area layers (themes) two fields are added to the layer's attribute table: i) Core Area and ii) Patch Area. Therefore be sure to choose the proper field to calculate statistics when analyzing core area layers (themes). 设置分析界限参数 Set Analysis Parameters
Fragstats还允许用户改变一些其他的分析参数，包括MPI的阈值，缓冲距离，文件名CWED，和边界的影响。这些参数的当前设置可以看出，在\分析参数\，\栅格数据空间统计\对话框的底部面板。要更改其中的任何设置，点击\设置分析参数\按钮。
Fragstats also allows the user to change some other analysis parameters including the MPI Threshold, Buffer Distance, CWED file name, and the Boundary Influence. The current settings of these parameters can be seen in the \bottom of the \Statistics for Grids\dialog. To change any of these settings, click theSet Analysis Parameters button.
空间分析输出表格
Spatial Statistics Output Table
从景观格局分析创建的空间统计输出表中查看分析结果。无论分析栅格数据还是矢量图层，前四列/字段将永远是相同的。这四 个字段分别为：i）数据名称，II）分析日期，III）运行（运行数）和 IV）类型（类统计代表某个特定的行）。如果是在景观水平上进行分析，类型字段将报告整体的。下面表中的字段包含\空间统计\对话框中选定的统计项。作为 一个完整的清单，包括缩写和单位，参考统计项汇总表（附注1）。每个统计项的一个完整的定义，也可在函数定义（附注2）页面找到。
The spatial statistics output table created from a landscape pattern analysis contains the results of the analysis. The first four columns/fields will always be the same regardless of whether a raster (grid) or vector layer (theme) was analyzed. The four fields are: i) (the name of the layer (theme) analyzed), ii) Run Date (the date of the analysis), iii) Run (the Run number), and iv) Class ( the class that the statistics for a particular row
represent). If an analysis is performed at the landscape level the Class field will report full. The following fields in the table will contain the statistics that were selected in the \Statistics\
abbreviations and units that the statistics are reported in refer to the Statistic Summary table. A full definition of each statistic is also available on the Metric Definitions page.
输出表将作为一个dBASE IV（DBF）文件被保存到用户指定的位置。在程序运行前系统将提示用户指定输出表名称及其位置。
