降级恢复

Due to serious soil and water loss, the ecosystem on the Loess Plateau is in a seriously degraded status. Discussion about the tendency of plant diversity change during the natural recovery process of vegetation in the studied area is very important both in theory and in practice.
黄土高原地区由于强烈的水土流失生态系统处于极度退化的状态，探讨该地区植被自然恢复演替过程中植物多样性的变化规律，对于指导该地区的人工植被建设具有重要的理论价值与实际意义。
Through simulation experiments, can automatically restore degraded image, there is a certain degree of noise immunity, and recovery effect is obvious. 2.
经过实验仿真验证，可以实现退化图像的自动复原，具有一定的抗噪性，复原效果明显。
At last, we have extended out algorithm from to gray image restoration to color image restoration, and realized color image restoration. ( 3) Several groups of blind restoration experiments for the degraded images had been conducted using our image blind recovery algorithm.
最后本文将提出的改进盲复原算法从灰度图像推广到了彩色图像复原，实现了彩色图像盲复原。（3）基于本文改进的图像盲复原算法，进行了图像盲复原实验。
