The monitoring method of the surface vegetation based on the spatial variation analysis

Based on the geostatistics analysis, the spatial variation analysis algorithm was conducted to calculate the range value according to each pixel with R which was outputted with the image data form. The analysis of the temporal and spatial distribution characteristics of the surface vegetation in the western of Jilin showed that they had regional characteristics. The range value of the surface vegetation in Zhenlai (north of the studied area) which was 13~14.5 ten days and 195~220 d was significantly lower than that in Tongyu (south of the studied area) which was 15~16 ten days and 225~240 d. The range value of the surface vegetation coverage changed due to the difference of surface vegetation types. The range value of the surface vegetation in Zhenlai was more regular than the other areas, while that in Tongyu had large fluctuation range due to the relatively complex earths surface vegetation. The range value of the surface vegetation in the wetland was special as the special surface vegetation which concentrated within minimum variation value (less than 12 ten days, 180 d ) and had significant different with other areas. The present study analysis the spatial distribution of vegetation after extraction of temporal changes in vegetation using semivariance function which provided a new method for the remote sensing interpretation research.
