Abstract:

There are growing concerns on the sustainable management of grassland plant resources in Northeast China because of the decreasing area of grasslands as well as the increasing number of rare and endangered plants with the intensification of human activities. To solve the issues of huge data of plant resources with multiple formats and difficulty in sharing, a WebGIS-based plant information system for grasslands of Northeast China was designed and developed using structure of B/S and Java language.The environment of platform development was MyEclipse2014 under the operating system of Windows 7. It was highly efficiently supported by the front-end development and the data-base techniques, and provided thematic map services through the ArcServer supported by the WebGIS technique and the powerful spatial data service. The system consisted of five modules, i.e., attribute query, data analysis, thematic application, system management, and update and maintenance.Management platform achieved the function of temporal and spatial statistical analysis on grassland plant resources, livestock carrying capacity statistics and special application of grassland quality.

摘要：

随着人类活动的加剧，东北草地面积骤减，濒危珍稀植物种类增多，草地植物资源可持续管理受到广泛关注。为了解决草地植物资源大数据，多格式，难共享等问题，开发设计了东北草地植物信息平台。平台开发环境为MyEclipse2014，系统环境为Microsoft Windows 7，编程语言为Java，依托WebGIS技术，以强大的空间数据服务为基础，运用ArcServer提供的成熟地图服务，详细设计了平台功能结构和数据库结构。在优秀的前端开发技术和高效的数据库技术的支持下，平台提供了专题地图制作的功能，开发了属性查询、数据分析、专题应用、系统管理和更新与维护五大应用模块，实现了草地植物资源在时空上的统计分析、畜牧承载力和草地质量等专题应用的功能。
