海岛旅游者生态旅游行为浅析--以湄洲岛为例

随着生态旅游的兴起，生态旅游行为内涵不断地得到丰富.文章以深层生态学为基础，设计海岛生态旅游行为调查问卷，探索旅游型海岛游客生态旅游行为的特征和影响因素.运用SPSS19.0数据平台，分析了旅游者的人口社会学属性和生活经历对生态旅游行为的影响及影响强度.分析结果表明，我国旅游者比较缺乏深层生态旅游行为的品质，社会属性中的受教育程度是影响旅游者旅游行为的重要因素.同时，旅游者平时的环保习惯与旅行过程中的环保行为表现出一致的现象.     

深井孤岛工作面过探巷技术研究

邢东矿2225工作面为孤岛工作面,承受地压大,回采过程中经过2225探巷,巷道围岩破坏剧烈,尤其是底鼓变形严重,初期采取排木垛、打单体等措施在一定程度上控制了探巷顶板下沉,而工作面临近时在煤帮注化学浆形成锚注加固结构使煤体自身强度及承载能力显著增强,锚注加固结构具有较好的整体性和稳定性,从而实现工作面顺利回采。     

基于灰色关联分析的“白屋顶计划”评价模型

在已知人为热释放、风速、日照时数和相对湿度的前提下,以芜湖市为例,运用灰色关联分析求出以上四个影响因素对行为因子(城市热岛效应)的关联影响程度,算出日照时数在四个环境因子中的比重,从而将白色屋顶计划对城市热岛效应的作用量化,建立了灰色预测模型。通过回归分析计算白屋顶计划对城市温度的影响,最后将预测数据与真实数据进行对比,模型结果表明"白屋顶计划"是合理且可行的。     

基于MODIS数据的成都市冬季热岛强度分析

随着成都市的发展,热岛效应成为一个很重要的影响因素。本文选取2010年——2013年的遥感数据,计算出其最大热岛强度和加权热岛强度来分析热岛强度变化,计算出城市热岛比例指数来分析热岛发育程度,并从这两方面分析出成都市冬季的热岛特点,从而揭示出成都市热岛强度与城市热岛发育程度的变化趋势呈反比的规律。     

对虎在我国两大岛屿上分布的历史考察

通过对虎遗存与发掘出的历史文献记载分析、辨证可知,我国的海南与台湾两大岛屿不仅在史前有虎,而且分别延续到宋代与清初,这是对专家、学者迄今多认为我国台湾与海南向来无虎分布观念的突破。     

Diversity and dispersal history of the talitrids (Crustacea: Amphipoda: Talitridae) of Bermuda

Five taxa of talitrid amphipods were found in the archipelago of Bermuda, of which three were recorded there for the first time. Four of these are supralittoral wrack generalists: Platorchestia monodi BOLD:AAB3402, (a unique Molecular Operational Taxonomic Unit according to the Barcode Index Number system), a related species recognized by molecular methods, Platorchestia platensis BOLD:AAA2949, Mexorchestia carpenteri carpenteri BOLD:AAC1491 and Tethorchestia antillensis; and one a terrestrial leaf-litter generalist: Talitroides alluaudi. A key is provided to discriminate between the formally described talitrids of Bermuda. Dispersal mechanisms from the American continent to Bermuda were considered for all taxa based on species distributions along the North American Atlantic coast and also investigated by molecular methods, using genetic population differentiation and haplotype network analysis based on the barcode region of cytochrome c oxidase subunit I gene. For P. monodi BOLD:AAB3402 the genetic results suggest that some dispersal events occurred before human colonization of Bermuda but are equivocal about the source population and therefore the direction of dispersal. Some very recent synanthropic dispersal is possible with this species. For the other two species studied genetically, P. platensis BOLD:AAA2949 and M. c. carpenteri BOLD:AAC1491, the small population samples analysed support dispersal to Bermuda from the American mainland, before human occupation of Bermuda, although the available sample size was limited for these species. The available limited direct, non-genetic evidence supports synanthropic transport for Talitroides alluaudi. Platorchestia monodi BOLD:AAB3402 is found in the same wrack habitat as P. platensis BOLD:AAA2949 on Bermuda, apparently without interbreeding. No evidence was found that driftwood specialist talitrids had become established in Bermuda.     

Butterflies of Grand Cayman,a dynamic island fauna

The butterflies of Grand Cayman, West Indies, have been surveyed in 1938, 1975 and 1985. Results of these surveys, together with information from other sources, are examined and it is shown that 46 species have been recorded, 8 of which are considered as vagrants and 38 as breeding species. Of the latter, 7 are believed to have become extinct and 6 are new colonists within the span of almost fifty years. The island can apparently support about 30 co-existing breeding species. These findings are discussed in terms of island biogeography theory. Grand Cayman data fit a species area regression for other West Indies islands very closely if only breeding species are considered.

Psocoptera (Insecta) from Bermuda

Seventeen species of Psocoptera are recorded from Bermuda, increasing the known number from three. Four new species are described: Echmepteryx atlantica n. sp., Caecilius bermudensis n. sp., Indiopsocus hilburni n. sp., and I. nebulosus n. sp. The latter two species appear to be closely related and two alternative hypotheses are proposed for their origin. Ectopsocus spilotus Thornton and Wong is recorded outside the central Pacific area for the first time. The species are assigned to four categories according to probable duration of time on Bermuda and probable source of original invaders: (1) endemics (four species); (2) species with wide distributions in the tropics and subtropics, not restricted to islands and sea coasts (four species); (3) species largely restricted to sea coasts and islands, not necessarily tropical (three species); (4) species widely distributed in southeastern United States, not restricted to the sea coast or the subtropical region (five species).
