【摘要】 随着经济的高速发展,人民的生活节奏越来越快。为了减轻工作压力,越来越多的城市人愿意在空闲时候,走出喧闹的都市,去感受大自然的所带来的轻松。所以近年来,越来越多的人喜欢在春季来临的时候到郊外赏花。那么能知道在何时、何地能看到最典型、最美丽的景色,对于出行者选择出游地点来说无疑有很大的帮助。在东北地区,紫丁香是一种广泛分布的观赏性植物,而且紫丁香进入花蕾期的时间比较早,花期时间又长。东北地区多种在春季开花的观赏性植物,如:杏、梨等植物,进入花蕾期的时间要比紫丁香晚,但进入未花期的时间却比紫丁香早。所以本文选用紫丁香做为东北地区赏花旅游资源的代表性植物。本文根据东北地区紫丁香物候观测资料,应用物候学原理,并利用东北地区33个气象站点近20年的气象观测资料,采用克里格插值等数学方法和地理信息系统(GIS)技术,从空间和时间的角度上,研究出东北地区紫丁香主要花期的时空分布特征,以及紫丁香开花期间东北地区气候适度的时空分布特征。并将上述两方面研究结果进行综合分析,从而分析出东北地区可以在什么时间、在什么区域,在最舒适的气候条件下从事赏花的活动。更多还原

【Abstract】 The step of modern life is faster than before because of the economic development. To relax and enjoy the nature, more and more people would like to go out of the city in their spare time. More and more people go out to enjoy flower in spring. It is valuable to the travelers to know when and where to view the beautiful landscape.The lilac is a widespread ornamental in Northeast in China. The lilac has a long florescence and the bud time is early. The bud time of the other spring ornamentals such as apricot and pear is later than lilac but the end time of florescence is earlier than lilac. The lilac is chosen as the representative ornamental in Northeast in this paper.Based on the Pheology data about lilac in Northeast and the theory of Pheology, this paper uses about 20 years of the data of 33 stations to study the florescence of the lilac. Kriging interpolation and the GIS are used here to study the temporal and special florescence characters of lilac. Besides the florescence of the lilac, the climate coziness index is discussed. Then it is identified that when and where to view the flowers under comfortable condition based on the coziness index in Northeast China.更多还原
