突变理论是研究客观事物过程由渐变引起突变的一种有效的新兴系统理论与方法.将多个评价指标合成一个与最优评价方法的接近程度，用来评价生态系统恢复状况.针对生态恢复演变过程的突变特征建立了生态恢复评价指标体系，采用突变级数法运用 ENVI4.2、ArcGIS9.2、MATLAB7.0等3S 技术平台对长汀县朱溪小流域生态恢复进行了定量评估和动态趋势分析；研究结果表明：（1）朱溪小流域生态恢复总体较好，80%的流失区都可恢复到Ⅲ级以上（含Ⅲ级）；（2）对长汀朱溪小流域生态恢复主要的影响因素是植被盖度；（3）突变级数法和生态恢复的交叉融合具有重要应用价值和实践意义.研究认为，采用了突变级数法进行综合评价不仅避免了人为制定权重的主观性，也反映了南方红壤侵蚀小流域生态恢复演变过程的突变特征，更为科学地揭示了生态系统恢复变化过程的本质规律.

Catastrophe theory is an effective and new system theory and method which are to study the process of objective things. Several evaluation indexes compose an evaluation menthod approaching to the best to evaluate the ecosystem recovery. According to the mutation characteristics of ecological restoration and evolution process, this paper establishes the evaluation index system of ecological restoration,adopt to the catastrophe progression method using 3S technology platform,such as ENVI4. 2,ArcGIS9. 2,MATLAB7. 0 and so on,to quantitative assess and use dynamic trend analysis on the ecological restoration of Zhuxi small watershed;The results show that(1)Zhuxi small watershed ecological restoration is good on the whole,80% of the erosion area can be recovered to grade III and above(including grade Ⅲ);(2)vegetation coverage is an important affecting factor for Zhuxi small watershed ecological restoration;(3)the integration of catastrophe progression method and ecological restoration is of great application value and practical significance. Studies suggest that catastrophe progression method not only avoids the subjectivity of artificial weight,but also shows the mutation characteristic of ecological restoration process in southern red soil erosion in small watershed,revealed the essential rules of changes in ecosystem restoration process.
