Chapter 9 is conclusion and future prospect. There are five innovative findings in the paper. Firstly, the evolvement of extensions and connotations of two reengineering styles is analyzed based on their high risk, and finding their trends of amalgamation. With this, the concept of corporation reengineering is then redefined combining core competence theory and ideas of process change management, and decompounding it into two parts: pre-reengineering and post-reengineering. Its inner relationships are analyzed and explained by economics theory. Secondly, establishing a analysis framework of reengineering risks, risk factors of foreign BPR are analyzed and concluded systematically for the first time. Reengineering risks are divided into three parts: plan, design and executive based on process and project management, then risk factors system is abstracted. Thirdly, 72 reengineering corporations in Jiangsu province are investigated on risk condition. Furthermore, risk factors in every part are analyzed and reduced experimentally by factor analysis method, and a risk factors system to suit Chinese corporation's reengineering is established. Fourthly, setting up a choice model of reengineering projects, the objective optimization model is presented to ascertain the weigh of each factor, a method of sequencing reengineering projects is presented so that risk of each reengineering project can be evaluated and compared effectively. Fifthly, an integration relationship model among IT, BPR and strategy is established aiming at productivity paradox derivative from IT and its dual effects on BPR, IT investment priorities in BPR is narrated deeply.

本论文的创新点体现在五个方面：1）基于上述两种重组方式的高风险性，对它们的外延和内涵演变进行了分析，发现它们日益融合的趋势；然后结合核心能力理论和流程变革管理的思想对企业重组的概念进行了界定，将其分为&前重组&和&后重组&两部分，并对其内部关系进行了详细分析，同时应用经济学理论对其进行了解释。2）建立了重组风险的分析框架，并首次较为全面地分析和归纳了国外企业重组的风险因素，根据重组的过程和步骤以及项目管理的观点，将重组风险划分为计划、设计和执行3个部分，并在此基础上提炼出企业重组的风险指标体系。3）运用现场访谈、问卷调查的方法，调查了江苏省72家企业重组的风险情况，然后利用因子分析法对每一部分的每一风险因素进行实证分析，对风险指标进行了约减，建立了比较完善的适合我国企业的重组风险指标体系。4）建立了重组变革方案的选择模型，然后针对不同的重组方案提出了确定指标权重的目标优化模型，并基于三角模糊数之间两两比较的可能度概念，提出了一种重组方案排序法，从而可以有效地对各种变革方案的风险进行评估和比较。5）针对信息技术所造成的&生产率悖论&现象及其对重组的双重影响，建立了信息技术、企业重组和企业战略之间的整合关系模型，并对重组中信息技术投资的优先权问题进行了深入的阐述。

It is shown that it is difficulty to differentiate each vegetation type among sub-tropical evergreen forest, sub-tropical coniferous forest and sub-tropical deciduous forest because of the mixture of their tree spectra. According to the reflection index in the wavelengths of 750 nm to 1 100 nm, the tree species can be divided into 4 groups with descend in reflectivity. Each tree specie can be differentiated from each other according to its slope of the spectrum curve and its reflection index in the wavelengths of 770 nm to 1 010 nm for each forest vegetation type. The unique first order derivative feature can be used to identify litsea, alder, fir, red birch, southwest birch, large schima confertiflora, taiwania flousian and small leaf schima confertiflora.

研究表明：亚热带常绿阔叶林、亚热带针叶林和亚热带落叶阔叶林等植被类型，因其树种间光谱特征混淆严重，而难以彼此区分；根据其反射率在750~1 100 nm范围上的差异，可将其归为4类；就各植被类型而言，其树种间在光谱曲线坡度，以及在770~1 010 nm范围上具有显著差异，可据此将其区分；木姜子、桤木、杉木、红桦、大叶木荷、秃杉和小叶木荷等因具有独特的光谱一阶导数特征，据此可以识别提取。
