Plant Suitability Evaluation System Research

Plant evaluation is used to evaluate the growing suitability of a plant in a certain area,accurate suitability evaluation is a vital part in realizing suitable plant in suitable area.Suitability evaluation based on raster pixel will put the evaluation result on accurate parcel which will cost less time and manpower.The article combines the most popular big data research method,pointing out the problem about how to select suitable plant on a large area,designing the system and work out evaluation based on overlay analysis method.The evaluation's based cell is grid pixel and use conditional analysis to calculate.The result will be shown in evaluation picture.The evaluation result can be further used in the research with more details and provide macroscopic gist for the actual production.The article's main results are listed as below:(1)Building the evaluation model:The article uses restriction and suitability factors which are determined by reading journals,consulting experts and application anlaysis.These factors are used to build evaluation models along with overlay method.(2)Building the system' framework with based on with the guidance of thesis in software engineering,the article used need analysis,system overall structure,.Net framework,VS2010 platform,ArcEngine as secondary development platform.The system uses Geodatabase and Oracle to save spatial data and SQL to save attribution data.(3)The result and data analysis:based on the system designed,the article choose 3 types of plant and their specific evaluation factors for evaluation and compare to the data which have been researched in other papers.The result conforms to the production and has a good application value.
