Importance of habitat type classifications for predicting ruffed grouse use of areas for drumming

To incorporate ruffed grouse (Bonasa umbellus) habitat planning in forest management, it is necessary for managers to understand factors contributing to grouse habitat use. Previous studies examining ruffed grouse drumming habitat documented relationships between drumming grouse and broad vegetation categories (e.g., northern hardwoods, young aspen [Populus spp.], oak [Quercus spp.]), but few studies have documented how drumming grouse respond to ecological variations in site conditions of aspen or other vegetation types that might be used. Our objectives were to determine the utility of habitat type classifications in predicting the occurrence of ruffed grouse drumming habitat in the western Upper Peninsula of Michigan, and demonstrate how classifications may be used to understand how forest management may affect ruffed grouse habitat. We used survey routes on state land and conducted drumming surveys during mid-April and early May at 78 points in 2005 and 2006. We recorded the number of drumming males heard at each point, the azimuth to where the grouse was heard, and a qualitative measure of distance to determine in which forest stands grouse were drumming. Using GIS, we determined the specific vegetation type, age class, and habitat type, evaluated habitat suitability, and determined a suitability score for areas in which grouse were drumming. We constructed a logistic regression model that calculated the probability of grouse use of areas for drumming based on vegetation characteristics at used and random locations. Our results indicated that the probability of grouse use of an area for drumming is based on inherent site characteristics (i.e., habitat type) and habitat suitability. The model is useful for planning forest management activities and understanding how grouse may respond to spatial or temporal changes in vegetation through succession or manipulation.

城市防灾避险绿地系统的构建

城市防灾避险绿地系统构建是城市绿地系统规划的重要内容。宏观上要在城乡总体规划的框架内,在城市抗震防灾等规划的指导下,构建与城市绿地系统规划空间层次相互衔接、逐级控制的防灾避险绿地规划体系;中观上要根据避险时序及空间关系等要素,对避险绿地、绿色疏散通道、隔离缓冲绿带等各级防灾避险绿地进行定量定位的合理布局;微观上要对每一块避险绿地、绿色疏散通道、隔离缓冲绿带进行深入与细化设计,共同构筑结构合理、层次清晰、分布均衡的城市防灾避险绿地体系。

氮肥运筹对陆两优996产量形成与氮利用效率的影响

以‘陆两优996’为材料,研究了氮肥运筹方式对超级早稻产量形成与氮利用效率的影响,结果表明：氮肥运筹方式显著影响超级早稻源库特性与产量,与D2处理（6:2:1:1）相比,D3处理（4:2:3:1）穗分化期略有延长,穗粒数略有提高,成穗率、有效穗数与叶面积显著提高,茎鞘物质输出率显著下降,产量显著提高;氮肥运筹方式显著影响超级早稻氮利用效率,与D2处理,D3处理氮素累积量、氮肥利用率、氮素吸收效率、氮肥效率显著提高。可见,适当增大穗肥比例有利于改善超级早稻源库关系,有利于提高产量、氮肥利用率与氮利用效率。
