摘要
利用1991~1993年在新疆阜康县不同草地类型上观测到的牧草产量、环境资料与地面光谱、气象卫星资料等,进行了多重相关分析。结果表明,不同类型的草地产量和环境因子与各种遥感绿度值间存在着显著相关性(P<0.05),相关系数(r)均达到0.84以上.并通过F检验.通过3年多研究,主要运用确定性强的遥感、环境和牧草产量及其它土地资源资料,借助于计算机和GIS,开发和建立了遥感环境综合技术系统(RSECTS)。利用NOAA气象卫星信息和ERDAS软件,进行了阜康县草地类型分类、草地和土地类型图及产量分级图制作,建立了NOAA卫片目视解译标志。并且利用RSECTS系统,对阜康县草地与其它土地资源进行了大面积动态监测与分析.研究发现,1992年该县的草地与其它土地资源比1982年前有较大变化,其研究结果也证明,利用NOAA气象卫星资料可进行草地和其它土地资源初级生产的动态监测.
Using the herbage yields, environment,spectral and synchronous NOAA/AVHRR Data observed in 1991-1993 in different grassland types in Fukang county,Xinjiang,the correlation analysis were made in the paper.The results showed that there existed an obvious correlation between the herbage yields and environment factors and various vegetation indices (P<0.05),the correlation coefficients were above 0.84 and passed the F test.Through over three years study,the Remote Sensing Environment Comprehensive Technology System (RSECTS) was developed and established by the computer using mainly clearer and more definite remote sensing,environment and herbage yield data.Using NOAA weather satellite data and ERDAS software,grassland type surveys and charts and yield classification maps were made in Fukang and the marks of explainning the NOAA satallite films were set up by the sight technology.Further,the dynamic monitor results of the grassland and other earth resources were analysed and studied by the RSECTS in Fukang,the study found that the grassland and other earth resources in 1992 had greatly changed than those in 1982 in Fukang.The results showed that the dynamic monitors of grassland and other land resourceprimary production could be made feasiblely using NOAA weather satellite data.
