Kindergarten Geography: Teaching Diversity to Young People

Abstract

A Southern Poverty Law Center grant enabled purchasing dolls representing children of different races, ethnicity, and condition of disability. The teacher used these with other materials to sensitize kindergarten children to human differences. She directed them to cut pictures from National Geographic Magazine showing people who are “somehow different/' Responses from children were classified. Nine commented on adornment, three on household setting, two on occupation, and one on race. Little research exists on teaching geography to kindergarteners except on the ability to read maps. The authors contend that kindergarteners are quite ready to learn about regional differences among human populations.

间歇性输水影响下的2001-2011 年塔里木河下游生态环境变化

采用2001-2011 年野外调查资料和卫星遥感影像数据,对生态输水影响下的塔里木河下游地下水、植被变化特征进行分析,并探讨了典型断面植被对地下水埋深变化的响应关系。结果表明:(1) 各断面地下水位变化过程与河道来水过程密切相关,近10 年来经历了显著抬升(2000-2005 年)—缓慢降低(2006-2009 年)—小幅抬升(2010 至今) 的过程,主要表现为随生态输水量的改变呈波动变化;地下水位抬升幅度与生态放水量的相关系数达0.78,与生态放水持续时间的相关系数为0.70。(2) 2001-2011 年塔河下游植被覆盖面积总体上呈增加趋势,其中灌木林地和草地变化显著,林地和耕地面积呈小幅度变化;植被覆盖度的变化主要表现为2001-2006 年显著提高和2006-2011 年小幅变化。(3) 植被覆盖度随地下水位的抬升呈现出增加的趋势;垂直河道的方向上,同时期植被覆盖度与地下水埋深空间分布特征一致,均以输水河道为轴向两侧植被覆盖度(地下水埋深) 逐渐降低(增大);平行河道的方向,植被覆盖度对地下水埋深的响应幅度随着离大西海子水库距离的增加而减小。     

Demographic Transition: Threat to Developing Nations

Abstract

As computers become commonplace in the nation's schools, interactive maps are finding their way into the geography classroom. Students can use electronic atlases to access information as well as use authoring software to produce their own interactive maps. Does this change in media correspond to better geography education for our children? This article addresses whether using interactive maps for gathering and presenting information can have a positive influence on learning geography content. A two-week experiment was conducted in five 7th grade classrooms. Students in four of the classes researched and produced map products using both traditional and computer-assisted techniques. The fifth class was a control group. A pretest and two post-tests were given to quantitatively assess student learning after each project. Also, students were given a qualitative questionnaire to determine their attitude towards the different techniques. Quantitative results of the study indicate that there was no significant difference in student post-test performance after using each of the techniques, but qualitative results suggest that students prefer using the computer techniques over the traditional methods for gathering and presenting information.

It provides the novice with a definition of remote sensing, information about some remote sensing products, data that can be obtained from remote sensing images, what can be done with images, ideas to integrate remote sensing with other subjects, a sample unit using images, and a list of associate areas related to remote sensing. The article also contains information for obtaining remote sensing materials and information and considers values concerns relating to remote sensing.     

The influence of bottom vegetation on remote sensing bathymetry: A case study using Landsat Thematic Mapper data in the Zanzibar Channel

By using echo-sounding data and considerable local knowledge of the environment the possibility to use data from Landsat TM for bathymetric mapping is analysed in the vicinity of Zanzibar. Different TM band combinations and basic image processing techniques are evaluated against the known water depths. The limitations of remote sensing techniques for bathymetric mapping are discussed, with emphasis on the problem of differences in reflective properties of the sea bottom. A recommendation for an optimal empirical method is given.     

基于遥感和GIS的黄土高原中阳县土壤侵蚀评价

黄土高原地区是我国水土流失最严重的地区,定量评价土壤侵蚀量、土壤侵蚀强度及其空间分布特征,可以为水土流失防治措施的制定提供依据.基于遥感和GIS,应用修正的通用土壤流失方程(RUSLE)对山西中阳县土壤侵蚀进行评价.结果表明,中阳县平均土壤侵蚀模数为2 874.25t/(km2·a),属于中度侵蚀地区,年平均土壤侵蚀量408.78×104 t.发生中度以上土壤侵蚀面积占总面积的29.95％,土壤侵蚀量占总侵蚀量的85.61％,这部分土地是土壤侵蚀防治的主要区域.黄土区发生轻度以上土壤侵蚀面积大,所占比例多,侵蚀程度严重.微度土壤侵蚀面积以有林地为主,轻度和中度土壤侵蚀面积主要是未成林造林地和灌木林地,发生强烈以上土壤侵蚀面积主要是疏林地、未利用地、灌木林地和农田,土地类型、植被覆盖与土壤侵蚀有着密切关系,林业生态工程建设对于中阳县控制水土流失和改善生态环境有着重要作用.     

水汽吸收和下垫面发射率对晴空大气红外窗区遥感影响的综合分析

从数学上探讨了晴空大气红外窗区通道遥感陆面特性水汽吸收和陆面发射率的综合影响。首先,基于辐射传输方程推导出大气水汽含量和陆面发射率(ε)引起红外窗区通道遥感陆面亮温(Tg)变化的数学表达式,指出红外辐射在传输过程中水汽吸收衰减的影响主要是引起大气透过率的变化;分析了在高温高湿和低温干燥等不同地区,红外窗区通道的大气透过率所受到的不同程度的衰减,以及水汽吸收衰减和陆面发射率对不同的红外窗区通道的影响。此外,还建立了一个红外窗区通道遥感陆面温度与地面亮温差ΔT=(Ts-Tg,imax)与水汽含量变化Δq和陆面发射率ε的二元多项式拟合方程,进一步分析大气水汽含量和陆面发射率对不同的红外窗区通道遥感的影响;指出红外短波窗区通道不但受太阳辐射污染严重,而且受陆面发射率变化的影响激烈,特别是在寒冷干燥的亚北极冬季。最后强调,为了精确地反演陆面温度,最好采用热红外窗区通道;必须考虑大气订正,特别是在高温高湿区;同时应该考虑陆面发射率等因子的作用。     

Grassland degradation in the “Three-River Headwaters&rdquo|region, Qinghai Province

Supported by MSS images in the mid and late 1970s, TM images in the early 1990s and TM/ETM images in 2004, grassland degradation in the “Three-River Headwaters” region (TRH region) was interpreted through analysis on RS images in two time series, then the spatial and temporal characteristics of grassland degradation in the TRH region were ana-lyzed since the 1970s. The results showed that grassland degradation in the TRH region was a continuous change process which had large affected area and long time scale, and rapidly strengthen phenomenon did not exist in the 1990s as a whole. Grassland degradation pattern in the TRH region took shape initially in the mid and late 1970s. Since the 1970s, this deg-radation process has taken place continuously, obviously characterizing different rules in different regions. In humid and semi-humid meadow region, grassland firstly fragmentized, then vegetation coverage decreased continuously, and finally “black-soil-patch” degraded grassland was formed. But in semi-arid and arid steppe region, the vegetation coverage de-creased continuously, and finally desertification was formed. Because grassland degradation had obviously regional differences in the TRH region, it could be regionalized into 7 zones, and each zone had different characteristics in type, grade, scale and time process of grass-land degradation.
