- 摘要:
- 通过运用GPS(全球定位系统)采集地块信息,结合地理信息系统(GIS)技术,进行数据处理,创建数据库、地图生成等操作,并应用克里格(Kriging)插值法生成杂草空间变异图,对苜蓿种植区域杂草空间变异特征进行分析。结果表明:生成的杂草种群空间变异图能够根据杂草种群相对多度的斑块大小、形状及空间分布等特点,了解苜蓿人工草地杂草种群的空间分布、变异特征,实现杂草的分区管理,为苜蓿人工草地合理管护、实行分区管理提供理论依据。
- Abstract:
- Throug happlying GPS to collect mass information,combining geographic information system(GIS)technology,the space variation diagram of weeds were produced by processing data,establishing database and drawing maps with applying Kriging value-inserting method.The results showed that the produced map could understand the spatial distribution and variation characteristics of manual weed population according to the features of plaque size,shape and spatial distribution of weed population relative abundance,realize weed region management.It could provide theoretical reference for rational manual weed management.
