摘要
总结了绿量的测量方法,包括叶面积绿量的测定方法和利用航空、航天遥感估算三维绿量的测定方法。分析了国内外在叶面积绿量和三维绿量方面的研究现状。指出了目前研究中存在着的对绿量的概念和内涵理解不同等问题。提出绿量估算的总体自动化、预测绿量的变化趋势等今后待加强研究的内容,指出应用遥感技术研究绿量是一种趋势。
This paper summarized green quantity measurement methods, including the determination of leaf area green quantity and three-dimensional green quantity measurement on the base of aerospace re- mote sensing estimation, also analyzed the research advances on green quantity of leaf area and three-di- mensional green quantity at home and abroad. Pointed out issues of misunderstanding on the concept of green quantity, also proposed that monitoring the change trend of green quantity should be strengthened and the application of remote sensing technology on green quantity would be a trend in the future.
