西部开发背景下贵州红色题材影视创作的现实思考

在红色题材影视创作的书写系统中,贵州被加工成梦幻奇观、英雄神话的空间固然能够为受众提供某种程度上的观赏性消费满足,但是,决不应该让视听文本里的"西部空间"失去自治性、多样性的可能去受控于市场操作的过程;贵州不应是一个从现实中被抽离出来并放置到梦幻和神话表意系统中的、抽象的、空洞的符号,而应是一个建立在现实地理空间基础上的、具有区域特征和民族文化特色的、历史与现实相生的人文系统。     

广西锰矿废弃地优势植物及其土壤重金属含量

调查了广西平乐、荔浦、八一3个锰矿区废弃地植物,对13种优势植物及其土壤重金属含量进行测试和分析。结果表明,白茅、马唐、飞蓬、苍耳、耳草对重金属有较强的耐性,可作为生态恢复的先锋植物;木荷、商陆是Mn污染土壤植物修复的理想物种;地瓜榕是矿渣、尾矿坝等严重污染区良好的恢复植物。人工复垦种植的果树和经济作物,其食用部分ωPb、ωCr、ωCd均超标,故矿山恢复早期不宜直接种植果树和食用经济作物。     

1978年以来广西耕地数量变化及其驱动因子分析

利用广西历年统计资料分析了1978—2005年广西耕地变化过程,耕地总量波动递减,人均耕地明显持续下降.耕地减少构成主要是建设占用耕地、农业结构调整占用耕地、生态退耕、灾毁以及其它;人均耕地面积逐年减少;个别年份耕地面积减少幅度很大;水田面积逐年减少,旱地面积逐年增加并趋于稳定,两者在耕地面积中所占的比例发生较大变化;农作物总播种面积呈上升态势,粮食作物播种面积总体上呈下降趋势,年际间有起伏.并分析了耕地变化的驱动因子,最后提出了耕地保护的措施建议.     

Muhaka icipe,an enigmatic new genus and species of Kleidotomini (Hymenoptera: Figitidae: Eucoilinae) from an East African coastal forest

A remarkable new eucoiline genus and species, Muhaka icipe, is described herein. The genus is clearly a Kleidotomini, but is distinguished from other genera in the tribe by a unique head and scutellar morphology. The genus belongs to the ‘wedge-head’-syndrome group of species that, to date, is unique to Afrotropical eucoilines. The new genus and species is reminiscent of Stentorceps Quinlan and Nanocthulhu Buffington, but is readily distinguished from these genera. Muhaka was collected from a threatened kaya (sacred forest) of coastal Kenya. The biological importance of this and other kaya forests, as well as their protection, is discussed.

广西小城镇地域空间结构特征及其发展探析

受区位因素、自然条件、经济社会发展水平和基础设施状况的影响,广西小城镇发展极不平衡,分布总体上东密西疏,且有明显的沿河流和交通干线及平原分布的特征,并形成四大城镇空间发展区,构成了广西小城镇的网络结构系统;针对小城镇发展腹地特点,不同地区的小城镇发展重点也应有所区别.     

广西丹霞地区文化旅游资源深度开发研究

随着旅游业的迅猛发展,传统观光旅游方式已不能满足广大游客对精神体验的需求,发展文化旅游迫在眉睫.广西丹霞地区文化旅游资源丰富,应加快发掘物质性和非物质性历史遗存,在充分研究其文化生态的基础上,通过旅游线路合理设计及媒介宣传等措施,实现丹霞地区及其周边地区文化旅游资源深度开发,把广西旅游业推上一个新的水平.     

A new species of the subterranean genus Oodinotrechus Uéno, 1998, from northern Guangxi,China, with additions to the generic diagnosis (Coleoptera: Carabidae: Trechinae)

A new eyeless species, Oodinotrechus liyoubangi n. sp, is described from northern Guangxi. All specimens of this interesting species were collected in three limestone caves in Mulun National Nature Reserve of northern Guangxi, southern China. It is the second species for the genus Oodinotrechus Uéno, 1998, distinguished from the type species O. kishimotoi Uéno, 1998 by its visible scutellum and pronotal structure. Several additional diagnostic characters for the genus and a geographical distribution map for both known species are also provided.
