Uniqueness of solution for generalized variational inequality related to strongly monotone Lipschitz mapping is shown. A sufficient condition is presented on the connectedness of solution set for the weak vector variational inequality on which the mapping is from a topological vector space X to L , where Y is also a topological vector space. The result is derived by discussing the properties of set-valued mapping induced by solution set of a scalar variational inequality related to the weak vector variational inequality.

Effect on birds community:Through the analysis of the correlation between the birds amount and frequency in the 9 parks and the 12 structure indexes of the parks,we reach the conclusion that Passer rutilans and Turdus merula are mostly effected by the area of the habitat, while Carduelis spinus,Parus venustulus,Aegithalos concinnus,Anthus hodgson,Paradoxornis webbianus and Trachybaptus ruficollis are mostly effected by humanlnterference.
对鸟类的影响:通过对市区9个公园的生境破碎化相关的结构、连通性、隔离度、人为干扰等12个特征变量与鸟类数量和出现频率的相关分析,发现常见鸟类中,麻雀和乌鸫对生境面积存在显着的相关关系;而黄雀、黄腹山雀、红头长尾山雀、树鹨、棕头雅雀以及小鸊鷉受到人为干扰的影响较为明显;白头鹎和珠颈斑鸠的数量与生境斑块的形状指数呈负相关;麻雀的数量随着斑块中灌木层密度的增加而上升;白鹡鸰随着乔覆盖度的增加而减少。

Patch characteristics indicated that the degree of fragmentation for the natural broadleaf forest was lower than for artificial landscapes of Phyllostachys pubescens, Cunninghamia lanceolata, and Camellia sinensis. Therefore, to maintain sustainable development in the region, and especially to enhance protection for the broadleaf forest matrix, intense human activity and tourism should be reduced.
