The surface of conventional engineering part is composed of simple analytical surfaces and four-boundary ruled surface primarily. Therefore a point cloud segmentation method based on those feature surfaces is proposed. Several algorithms to identify the simple analytical surface feature are investigated and discussed. The theory of fitting scattered point to B－Spline and Bézier surfaces is introduced and a fitting method based on four boundary and point set is also discussed. Moreover, anew method to recover the fix-radius rolling ball blend is proposed and discussed in detail.

It concludes that they are mainly succeeded in the subject structure of one plus four, four research layers and five hotspot research aspects. The defects are mainly laid on its lag to the construction of green land, inadequate research theory, weak schematism and inadequate work of quantification. Finally the paper puts forward prospects of Chinese urban green space system from six aspects.

总结了近10年来中国学者对城市绿地系统的研究成果，归纳其特点在于"1＋4"的学科结构、四个研究层面和五大热点研究方向，不足之处在于研究大大滞后于城市绿地的发展、研究理论深度不够、系统性不强以及量化工作不够，最后本文从六个方面提出了中国城市绿地系统的研究展望。

Further comparison of the vascular bundle sheath sclerenchyma cell deterioration in separate plants infected with an additional four CTV isolates, CTV-2, T-TX8, T-TX9 and T-TX24 showed that there were significant differences in scleranchyma cell deterioration in principal lateral vein, midvein, petiole, and healthy control with all four CTV isolates (P=0.000 1, F=80.60, df= 47). Healthy plants had no such sclerenchyma cell deterioration.

Based on the management principle and objective of Jiangsu SNWDP, the thesis establishes its management framework and designs three management patterns and four modes. Through analyzing the anticipative management effect, scopes in point, advantages and disadvantages of each modes seriatim, the thesis confirms the recommended pattern. It makes framework refinement design, defines rights and duties of control level, execution level and participation level for the recommended pattern. According to the principles of planned water use, metered water use, contract water use, toll water use, it studies project operation for recommended pattern from four aspects, namely water supply plan, measure intensified, water supply contract, and water rate enacted. The thesis analyses and studies how to ensure water supply quality of Jiangsu SNWDP from three levels, including doing watershed protection, intensifying intermediate process, and establishing a long-term mechanism. It makes brief design for dispatching management applied system, studies emphases parts which may affect operation of the pattern in practice, also analyses dispatching optimization of Provincial boundary project management, pumping station management, and different water resources. Finally, the thesis studies relevant basal supports and development stratagems for the management of Jiangsu SNWDP.
