| 摘 要： | 本文介绍了一种利用遥感图像数据及土地资源野外调查数据,在IBM—PC/XT微机上,建立区域性土地资源评价信息系统的方法。该系统可对土地资源进行高效、快速的周期性评价和自动制图。 系统采用网格方法对多边形图像进行特征编码及数字化输入,利用模糊数学的原理和方法,建立了土地资源适宜性评价的模糊动态聚类评价模式,并用模糊模型识别评价模式进行土地资源的质量评价。根据上述评价模式,系统可进行多层数字图像之间的逻辑图像运算,从而实现了土地资源评价过程的自动化。

| Abstract: | A regional Microcomputer land Resource Evaluation Information System (MLREIS) was set up in Microcomputer (IBM-PC/XT) by using image data of Remote Sensing and field-work data of Land resources. The MLREIS could be used for evaluating land resources efficiently, rapidly and periodically, and mapping automatically. The method of grids was adopted in the system to encode feature values of polygon figures and to input them with digi-tigation. On the basis of principle and methods of Fuzzy mathematics, the author built a Fuzzy dynamical clustering model of suitability evaluation of land resources, and presented a Fuzzy pattern recognition model to appraise the quality of land resources. In the light of the above appreciation models, the logical image operations among multiplayer digital pictures were carried out in the MLREIS and thus the process automation of land resource evaluation was realised. |
