为明确黄翅绢野螟Diaphania caesalis对不同植物的取食和产卵选择性,采用叶碟法、叶面积法和室内观察等方法比较分析了黄翅绢野螟对波罗蜜(‘马来西亚1号’‘海大1号’‘四季波罗蜜’)、榴莲蜜、面包树、大果榕和桑树(‘台湾长果桑’‘粤椹大10’)的取食和产卵选择性,取食面积及初孵幼虫取食不同植物后的存活率。结果表明,黄翅绢野螟1~2龄幼虫对波罗蜜的取食偏好不明显,对不同植物的取食选择率差异不大;随着龄期的增长,3~5龄幼虫逐渐表现出偏好取食波罗蜜。黄翅绢野螟在不同植物上的日均产卵量没有显著差异,偏好在波罗蜜和面包树上产卵,在‘马来西亚1号’波罗蜜上着卵量占所有供试植物上的总产卵量的22.13%。各龄幼虫对不同植物的取食量随着龄期的增加而逐渐增大,5龄幼虫进入暴食期,对3个波罗蜜品种、榴莲蜜、面包树和大果榕的取食量无显著差异,但显著高于2个桑树品种。初孵幼虫取食不同植物48 h后的存活率存在显著差异,取食‘马来西亚1号’波罗蜜存活率最高(98.51%),取食‘台湾长果桑’存活率最低(0.37%)。综上,黄翅绢野螟偏好选择波罗蜜属植物进行取食和产卵,对榕属大果榕存在转移为害潜在威胁,对桑属桑树潜在为害风险较低,研究结果可为黄翅绢野螟在不同植物上的为害风险监测和防控提供参考。

作者： Zhang Zhongbo xu dongying Wang Ling Weather Modification Office of Hunan Province Key Laboratory for Meteorological Disaster Prevention and Mitigation of Hunan Province

Based on NCEP 1°×1° reanalysis data, ground encryption houdy precipitation, FY-2E stationary satellite and Doppler radar data, the structural characteristics of precipitation clouds in Hunan Province and the effects of airplane precipitation operation were analyzed. The results show that under the effects of low-pressure system and southwest monsoon, Hunan was rich in water vapor, which was beneficial to the maintaining of precipitation clouds. During the process of the artificial precipitation operation over Hunan Province, convection developed vigorously, and precipita- tion was strong in the south of the province; embedded convective clouds were dominant and precipitation was weak in the east of the province. Cloud optical thickness correlated with ground precipitation positively. After catalyzing, echo at high altitudes responded firstly, and the echo intensi- ty increased gradually; the response of low-altitude echo lagged behind that of high-altitude echo. It shows that catalysis could lead to increase of upper precipitation particles in size and quantity. As time goes on, upper precipitation particles descended to low altitudes, so that echo intensity in- creased at low altitudes. It is clearly seen that catalysis could lead to increase of echo intensity and prolong the lifetime of target clouds to improve the area of strong echo zone, showing obvious positive catalytic effect. At the same time, houdy average precipitation in the affected region tended to increase stably and was obviously more than that of the contrast region where hourly average precipitation reduced gradually with time. The changing trend of hourly average precipitation in the affected region correlated positively with the response of radar echo.

公路风吹雪雪深预测作为国际雪冰学领域的研究热点和难点问题一直未能很好解决.以白茫雪山防雪走廊段安装的自动气象站和当地气象局提供的气象资料为基础,提取了对公路风吹雪雪深有影响的4种因素(降雪量、大气温度、风速和湿度)的指标值,建立了基于BP(back propagation)神经网络的公路风吹雪雪深预测模型.对研究区5次降雪过程中所记录的199组数据进行训练学习,用20组数据来验证建立的模型,验证结果表明20h累计雪深预测值的误差在10%以内,85%的雪深预测值误差在20%以内,因此所建立的模型具有很强的泛化能力和较高的精度.并对降雪量、大气温度、风速和湿度这4个因素进行了敏感性分析,表明雪深与降雪量成正比,与其他3个因素成反比,其中降雪量对雪深的影响最大,风速次之,湿度最小.

本文考察了主客同一研究范式的内涵、发展脉络及历史地位。作者认为,主客同一研究范式体现着心理学的人文科学定向,张扬的是人有别于自然物的“天使”形象,展示的是将人的心理、行为视作“生活”,试图从内部体验、直观以达成对人的独特本质洞察的“内观心理学”境界。它和主客二分研究范式均可在未来心理学中获得各自合理存在的空间。
