基于生态人类学的西藏原生态旅游研究

生态人类学是从生态学角度进行文化及其演化的阐释，把适应环境作为最重要的解释机制。文章梳理了西藏原生态旅游开发的优势与成果，分析了其发展中所面临的挑战，提出应转变观念、约束行为、尊重当地文化，以确保西藏原生态旅游可持续健康发展。     

Soil oribatid mite (Acari: Oribatida) diversity and composition in semi-deciduous forest fragments in eastern Amazonia and comparison with the surrounding savanna matrix

We recorded species abundance and richness of oribatid mites along 16 plots established in semi-deciduous forest fragments in Amazonia. The results were compared with a published dataset consisting of an inventory carried out in 38 plots in the surrounding savanna. Totals of 143 and 91 species were recorded in the forest fragments and savanna, respectively. Sørensen similarity index between both environments was 0.44. Ordination of sites according to oribatid mite species composition showed a clear separation between forest fragments and savanna. Rostrozetes ovulum, Archegozetes longisetosus and Eohypochthonius (Eohypochthonius) becki were abundant and frequent in the forest fragments but exceedingly rare in the savanna. Neoppia (Neoppia) schauenbergi, Pseudoppia sp. C, Microppia sp. A and Cosmochthonius sp. A were limited to the savanna. This study also represents an early step toward knowing which groups of species are exclusive to one or another vegetation type or are sensitive to their inherent environmental conditions.     

Morphology and biology of a new Rhynchospio species (Annelida: Spionidae) from the South China Sea,Vietnam, with the review of Rhynchospio taxa

Adults of a new spionid polychaete, Rhynchospio nhatrangi, inhabit sandy tubes on muddy sand intertidal flats in an estuary of Nha Trang Bay, southern Vietnam. The worms are up to 8 mm long and 0.5 mm wide for 55 chaetigers. They are unique among spionids in the changes in the arrangement of hooks during ontogenesis: first development of tridentate hooks in neuropodia from chaetiger 10, later loss of hooks in chaetiger 10, and replacement of tridentate hooks by heavy unidentate hooks in neuropodia of chaetigers 11–14. Adults are simultaneous hermaphrodites having sperm in chaetigers 11–14 and oocytes from chaetiger 15 to 23–33. Spermatozoa are introsperm, about 300 µm long. Oocytes are about 120 µm in diameter, with a thin and smooth envelope. Fertilization and early larval development occur in a hatchery formed by elongated dorsal capillaries on the posterior chaetigers. Larvae escape from the hatchery probably when they have developed four chaetigers and then continue development in seawater, feeding on the plankton. When larvae have grown to 14–15 chaetigers, they likely undergo gradual metamorphosis and settle on the bottom. Metameric nuchal organs, glandular pouches in neuropodia, metanephridial segmental organs, hermaphroditism, sperm, and early larval morphology are described here for the first time for Rhynchospio species. An identification key is provided to eight currently recognized Rhynchospio species.     

中越边境民族地区社会和谐发展制约因素及其对策探析——以麻栗坡县猛硐乡为例

中越边境民族地区的和谐发展存在诸多制约因素,诸如边贸互市规模小、新农村建设推进困难、经济落后、教育落后等等。改变这种面貌,需要多方面、多层次的支持与帮助。     

浙江基层干群民主素质状况调查和养成新途径探析

创新型高校运动俱乐部发展研究

传统高校运动俱乐部在提高学生的身体素质、运动技能等方面曾起到了重要的作用．但是，随着社会的发展及教育事业的进步，传统高校运动俱乐部在管理机制、运动形式、体育文化宣传及提高学生运动参与性方面显得较为落后，逐渐成为高校的“鸡肋”，变得较为尴尬．针对以上存在的问题，为改变目前高校运动俱乐部尴尬的地位，本研究以可持续发展观为指导，提出高校俱乐部必须创新管理机制、繁荣俱乐部运动项目、加强体育文化宣传、提高学生参与性的创-新发展路子，将高校运动俱乐部建成高校学生提高综合能力、增进学生交流、促进学校与社会接触的综合性实践平台．     

陕西学前教育发展前景综述

近年来,陕西省幼儿教育事业取得长足的发展,但也存在一些突出的问题。《国务院关于当前发展学前教育的若干意见》等文件的颁布,第一次提出＂把发展学前教育摆在更加重要的位置＂,给我省学前教育的发展带来了＂一个新的春天＂。对我省学前教育新政策进行分析,发现目前学前教育发展中存在相当多的问题,针对如何解决这些问题提出具体的建议。     

提升基础教育发展质量的若干思考

提升基础教育发展质量必须紧紧围绕发展这个中心,进一步更新发展理念、夯实发展条件、提高发展效能。在新的历史条件下,进一步提升基础教育发展质量既是学习实践科学发展观的迫切需要,也是构建和谐社会的迫切需要,同时还是建设创新型国家的迫切需要。当前,进一步提升基础教育发展质量,必须充分发挥地方政府的主导作用、学校主体的能动作用,以及社会各界的支撑作用。
