摘要
研究目的:利用遥感技术对土地复垦后的土地质量评价指标——植被覆盖度进行评价。研究方法:利用ERDAS软件通过建模实现植被覆盖度提取,对结果影像进行分级统计。研究结果:土地复垦后的试验区植被覆盖度比复垦前高。研究结论:评价结果符合实际情况,利用遥感技术对土地复垦后的植被覆盖度进行评价是可行的。
The purpose of this paper is to assess the vegetation coverage through Remote Sensing technology, which is one of the main assessment indicators of land quality after land reclamation. Methods employed include data extraction from vegetation coverage level by modeling with ERDAS IMAGINE software and the graded statistics analysis on the resulting imagines. The results indicated that the vegetation coverage after land reclamation is higher than before. It is concluded that assessed results conform to the actual situation, and the method of vegetation coverage assessment based on RS technology of vegetation coverage after land reclamation is feasible.
