| 摘 要： | 遥感信息是对自然界的反映，它具有宏观、动态、准确、快速的优点，可以及时提供动态数据。基于遥感信息，对吉林西部土地资源利用状况进行调查，运用主成分分析法，可以不损失或很少损失原有的信息，将原来个数较多而且彼此相关的变量转换为新的个数较少而且彼此独立或不相关的新变量。对土地资源可持续利用进行定量分析研究，指出土地利用中存在的问题，并提出吉林西部土地资源可持续利用发展模式。

| Abstract: | Remote sensing data is the reflection of nature,having the merit of macroscopic,dynamic and exact reflection with higher speed. Based on remote sensing data,land utilization of western Jilin Province is investigated.Taking the principal component analysis method,the intrinsic information may not be suffered lose or be lost less than before,which makes new independent variable less than intrinsic correlative variable in number. Quantitatively analysing the land resource sustainable utilization,the authors point out the main problems in land use,and propose the model for land resource sustainable utilization. |
