本研究利用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与环境因子和各种绿度值间存在着显著相关性(ρ<0.05),相关系数(r)均达到0.84以上,并通过F检验.又利用作者研制开发的遥感环境综合技术系统(RSECTS)进行了草地资源的系列动态监测与分析,建立了综合估产模型及相应的可利用牧草估产模型等;—同时,进一步运用RSECTS建立了草地利用和草畜平衡监测模式及进行了草畜平衡与管理诸方面分析和论证,基本实现了从初级生产到次级生产对草地资源的遥感动态监测,解决了许多有关技术性难题,找出草畜系统管理中存在的主要问题,制定了调控措施,为草地资源的科学管理与合理利用,提供了坚实依据和可靠方法.

Using the herbage yidlds,environment,spectral and synchronous NOAA/AVHRRData observed in 1991- 1993 in differentgrassland types in Fukang county,Xinjiang,the correlation analysis were made in thepaper. The results showed that there ekistedan obvious correlation between the herbageyields and environment factors and variousvegatation indices (P< 0. 05 ), the correla-tion coefficients were above 0. 84 and passedthe F test.Through over teo year study,the Re-mote Sensing Environment ComprehensiveTechnology System (RSECTS) was devel-oped and established by the computer usingmainly clearer and more definite remotesensing, environment and herbage yield da-ta, The system (RSECTS) had the macro-cosmic and microcosmic two side functions and effects,and it was also a more compre-hensive, convenient operational informationtechnology application system.The grassland resourse dynandc moni-toring and analysis and a lot of the geo-graphical, the optical satellite remote sens-. ting and comprehensive and relevant availu-able herbage models of estimating yieldswere established by the RSECTS made fromthe authores. The estimating yield accuracywas above 90% by the models;3 rte Projec-tion Pursuit Regression (PPR) Technologywas appliced in the herbage yield forecastsand set up of forecasting yield models, andraising the accuracy and effect of yield fore-cast. Further, using above the finest mod-els, real herbage yield forecast was made inthe thesis, the total accuracy was above75%. And the conversion coefficients ofwitheren grass yields in the winter and an-nual changing rates of herbage yields weresought up. However, the grassland utiliza-tion and forage-livestock balance monitor-ing models were also set up by theRSECTS,and a lot of forage-livestock bal-ance problems were analysed and discussed.The system remote sensing dynandc moni-tors in the grassland resource were realizedfrom primary productions tO secondary pro-ductions and a lot of relevant technicalproblems were solved. The main problemsin the forage - livestock system manage-ment were found,and the management con-trolling measures were made in the paper.Therefore, the scientific basis and methodswere provided in orde to realize the realmanagement and rational utilization grass-land resource.
