[ Method ] The needles of Pinus yunnanensis were mixed with the leaves of Cupressustondosa, C. cam- phora and C. Oerst according to the ratios of 0 g ： 6 g, 1 g ： 5 g, 2 g ： 4 g, 3 g ： 3 g, 4 g ： 2 g, 5 g ： 1 g and 6 g ： 0 g, and the mixtures were put in the re- spanse arm of Y-tube olfactometer as odor source to observe the olfactory behavior of T. yunnanensis, the empty arm was set as control. [ Result ] When the needles of P. yunnanensis were mixed with the leaves of non-hest plants according to the ratio of 1 g ： 5 g and 2 g ： 4 g, they had less difference on attractive rate to T. yun- nanensis compared with complete P. yunnanensis needles in mixture （ratio： 6 g ： 0 g）, and the maximum difference was 14%. When the needles ofP. yunnanen- sis were mixed with non-host leaves according to the ratio of 1 g ： 5 g, 2 g ： 4 g, the attractive rate to T. yunnanensis decreased compared with complete P. yun- nanensis needles in mixture （ ratio： 6 g ： 0 g）, and the decrease value in maximum was 40%. [ Conclusion] When the ratio of non-host plants was relatively small in mixed leaves, non-host had less impact on olfactory responses of T. yunnanensis. As the proportion of non-hest leaves gradually increased, the attractive rate of leaf mixtures to T. yunnanensis was gradually small. The results could provide reference for determination of mixed ratio in construction of mixed forest and the de- velopment of botanical attractive and repellent of T. yunnanensis.展开更多
By using GIS, RS and landscape ecology, LandsatTM (1993 and 2009) and ETM (2001) remote sensing images of Licheng District of Ji’nan City, Shandong Province were interpreted, and dynamic changes of landscape pattern ...By using GIS, RS and landscape ecology, LandsatTM (1993 and 2009) and ETM (2001) remote sensing images of Licheng District of Ji’nan City, Shandong Province were interpreted, and dynamic changes of landscape pattern in the district were analyzed at the levels of class and landscape. The results showed that during the 16 years the landscape pattern in the district had changed significantly. (a) From the perspective of patch category, areas of arable land, woodland and grassland decreased unceasingly, and arable land accounted for the largest reduction from 488.15 km 2 in 1993 down to 324.37 km 2 in 2009, witnessing a reduction rate of 33.56%. But the patch quantity and fragmentation increased, patch connectivity reduced. Spatial pattern of construction land expanded and its area witnessed a significant increase of 147.05%. Patch cohesion index increased and connectivity grew better. (b) From the perspective of overall landscape, patch quantity, contagion and perimeter-area fractal dimension decreased, patch shape became simple, the Shannon’s diversity index, Shannon’s evenness index and splitting index increased, landscape heterogeneity rose. With the rapid social and economic development, landscape pattern will be more and more influenced by human behaviors展开更多
