These characteristics account for the magnificent species diversity and high level of endemism. Insects of 45 000 species have been recorded in China by now.

这些特征可用来说明其丰富的物种多样性和高特有性，迄今中国已报道的昆虫种类约为45000种。

Potential Species' Distribution System, a new GIS-based system, has been designed and implemented to predict the potential distribution of species by using presence data only. The result, normally overpredicted by traditional Environment Envelope Model, is improved by using hierarchical cluster arithmetic that can reduce the influence caused by outliers.

在这一系统中，通过层次聚类算法对物种已知分布点数据进行处理，减少了异常值对预测结果的影响，从而解决了环境包络模型预测结果过于乐观的问题，在物种已知分布数据较少时也能取得较好的结果。

They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects. Our group has been engaged in researches on the photochemical properties and application to water pollution control of different ferric species including Fe -OH complexes, Fe -polycarboxylate complexes, Ferric oxides and Fe -humic acid complexes. Fe -oxalate complexes system has higher efficiency than the other ferric species systems in photooxidation and degradation of organic compounds. This thesis is focused on the photodegradation of nine EDs estradiol (E2), estrone (E1), 17α-ethynyl estradiol (EE2), diethylstilbestrol , bisphenol-A , 4-Nonylphenol , 4-Octylphenol , di-n-butyl phthalate , and di (2-ethylhexyl) phthalate .

因此从处理效率和环境化学意义两方面考虑，结合本课题组在不同铁形态（包括Fe-OH配合物、Fe-多羧酸配合物、Fe氧化物、Fe-腐殖酸配合物等）的光化学特性及其在水污染控制中的应用方面较系统的研究工作基础，本论文选择了四类共9种典型的内分泌干扰物（雌二醇（E2）、雌酮（E1）、17α-乙炔基雌二醇（EE2）己雌酚、双酚A、壬基酚、辛基酚、酞酸二丁酯和酞酸二乙基己基酯），研究了它们在Fe-草酸盐配合物体系中的光降解效果，推测其降解机理，探索环境内分泌干扰物光氧化处理的新体系，同时为预测其在环境中的光降解行为提供了依据。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
