基于遥感的土地利用景观格局指数程序开发与实现_英文_ Program Development and Implementation of Land- scape Pattern Indexes for Land Use Based on RS XIE Hong -quan ，DAI Di School of Geodesy , Geomatics Engineering，Huaihai Institute of Technology，Lianyungang，Jiangsu 222005，China Abstract Interpretation results of RS images were taken as the foundation，ETM RS images of July 15，2009 as the data source，ENVI was ap-plied for the preprocessing，Arc GIS used to finish the interpretation，master data obtained，and VB used to complete program development, 12 representative landscape pattern indexes were selected，Excel data used to create Access database，and VB used to complete the program devel- opment, Selection of landscape pattern indexes，program development process and program usage were summarized，through comparing its results with Excel calculation results，it was found that calculation results of this program were correct，the usage was convenient，so needs of most users could be satisfied, Key words Remote sensing，Landscape pattern indexes，Database，Program development Landscape change is a major content of researches onignifi-with simple calculation formulas and definite ecological s cance were selected to reflect landscape heterogeneity from global environmental change and land use / cover change different perspectives and quantitatively analyze land use land- ( LUCC) ，so RS-based landscape change research has already scape pattern in an all-around way, These indexes were patch become a hot spot in landscape ecology researches, GIS- density，edge density，landscape separation，landscape distance based FRAGSTATS quantificationana lysis of landscape pattern index，landscape area index，landscape diversity index，land- greatly facilitates quantificationr esearch of landscape ecology， scape evenness index，landscape fragmentation index，patch however，this software is less used because ofi ts inborn disad- ,1, fractal dimension，patch squareness index，patch near-circular vantages，most of researchers calculate directly in Excel with index and dominance index, Calculation formulas of these index formulas，but a large amount of calculation easily leads to indexes were shown in reference ,4, and ,5,,errors, In this study，ETM remote sensing images of July 15， 2009 were applied as the data source，ENVI for the prepro- cessing，ArcGIS used to finish the interpretation，master data 2Program

VB was used to finish the interface design，program coding，testing and debugging，inter- 1Selection of landscape pattern indexespretation and establishment of executable program，and finally operation of the application program, Landscape pattern is a configuration and combination of 2, 2 Database creation landscape elements in landscape spaces，and also a result of,2,2, 2, 1 Creating a new database, Access database software interactional landscape structure and landscape eco-process, was opened，database filename set in the window " Create a In the application，characteristics of differenlandt scape indexes， new database" ，" db1" input as the database name, goals and contents of researches should be fully considered to 2, 2, 2 Acquisitioning external data, " Import" in " Acquisition choose proper indexes to give the best quantified descriptiont o external data" in the menu of " File" was clicked，" File type" the study object, There are research works about the selection of chosen as " Microsoft Excel ( ,x ls ) " in the window of " Import" ， landscape indexes in China and abroad， all of these works the storage path of ,xl s files selected in " Search scope" and stressed that the simplest and the most persuasive indexes then the ,xl s files to be converted，" Import" clicked，( in this should be used，change trend and corresponding value of each study，data of 2009 was applied) ，the window of " Data import index should be known clearly，landscape size and grading should wizard" opened，the data import finished step by step accord- also be considered in the selection，index

worksheet，these headings should be deleted " Import data" clicked as Fig, 2 shows,first before data import，otherwise，headings would be imported into database as data, 2, 2, 5 Data saving, According to the default setting，data was saved in " New worksheet" , 2, 2, 6 Field setting, If " Column headings in the first row" was selected，column headings would be shown as the " Field name" ， otherwise，" Field name" would be " Field 1" ，" Field 2" etc, ，and a new field name of this column could be retyped, Major key was set to avoid data duplication，and also to accelerate data inquiry,De fault setting of " Add major key with Access" was selected, 2, 2, 7 Finishing data import, A worksheet under " Load data Fig, 2 Import datainfile" was created，then data imported into this worksheet with " Next" was clicked，index calculation window would pop " sarah" as the name，and then the data import finished, Back up，" Calculate and output" was clicked ( Fig, 3 ) ，calculation to the window of database，a datasheet of " sarah" would be results output in text files，and then " exit" clicked, seen，and the dbl, mdb created in this way was a real database,The n mdb files were copied to paths of VB
