| Abstract: |
| In order to monitor the change of natural rubber growth and estimate the potential of natural rubber production accurately and timely, to improve the production of dry rubber in Hainan and provide a basis for decision-making for the relevant departments, and realize the application and demonstration of FY-3 meteorological satellite data in natural rubber industry, which was the second-generation polar orbiting meteorological satellite in China. In this study, the NDVI of natural rubber at different times was compared and compared with the perennial average of the historical period to monitor the rubber growth potential, based on the meteorological satellite data of Fengyun-3, meteorological observation data of the same period and the planting information of Hainan natural rubber, etc. Combined with Carnegie-Ames-Stanford Approach (CASA) model, the net primary productivity estimation model of natural rubber was constructed, and then combined with the dry matter distribution ratio of natural rubber, the gum potential estimation model of natural rubber was constructed. On that basis, the remote sensing monitoring system of natural rubber growth potential and potential productivity of natural rubber in Hainan was designed and developed by C# language in Visual Stdio.net 2010 and MeteoInfo platform. The system was composed of four functions: basic data preparation, monitoring of natural rubber growth, estimating of potential productivity, and production of figure. Using the system constructed in this study, can timely understand the growth law of natural rubber and the change of rubber production potential, quickly grasp the impact of meteorological disasters on the growth of natural rubber, and provide technical and software support for improving dry rubber production. |
