The Application of Wavelet Transform in the Analysis of Leymus Chinensis Communities Vegettion Pattern

Based on the survey in the field, wavelet theory was adopted to analyze experimentally the distribution characteristics of Leymus chinensis vegetation coverage, on different scales in a 1000-meter-long sample belt. A suspending problem in studying simultaneously the vegetation pattern scale, intensity and grain on different scales was solved according to the analysis of projection figure of wavelet transform on different scales. This leads to find the feature that changes of vegetation pattern on different scales are consistent with fractal characteristics.
