Research on the Changes of Near Infrared Spectrum of Leaves Menaced by Water

Previous research has shown that the near infrared spectrum of leaves of plants starts to change in intravital trees or other vegetation, but there has been little related research on leaves fallen from vegetation and we design a experiment to study this aspect. Because of different water losing rates of leaves, different leaves present different changes. As to the change of the red edge and related parameters, we think the main possible reason is that the difference in life-form characteristics and vitality of species. This provides the basis for applying remote sensing to monitor the biological changes of vegetation stressed by a drought season. Whether other growth seasons will also present similar changes needs to be studied further.
