Internet‐Based GIS Mapping in Support of K‐12 Education

Internet‐based mapping provides a powerful alternative for successfully establishing GIS technology in the K‐12 education community, while simultaneously avoiding the traditional barriers associated with desktop GIS. Internet‐based GIS can support standards‐based inquiry methods of teaching and learning while providing basic analysis tools for studying and exploring geographic or scientific data in the classroom.     

Development of an integrated conceptual model for the rational management of the transboundary Nestos River, Greece

This paper provides a detailed analysis of the geologic, hydrologic and hydrogeologic characteristics of Nestos River basin, which is formed within the Greek mountainous part of the river. The quantitative analysis was mainly based on the data of the river flow in different gauging points across the rivercourse as well as on the data of groundwater discharge from karst springs of the mountainous area while important conclusions were made regarding the hydraulic connection between the surface waters of the river and the groundwater of the karst aquifers of the basin. The qualitative analysis has shown that the quality of both surface waters and groundwaters of the investigated basin is high, whereas, no sources of contamination were indicated during this research. The possible effects of the two large dams of Platanovrisi and Thesavros are also analysed as they strongly affect the quantitative and qualitative regime of the river delta.

新亚欧大陆桥(河南段)经济带地下水资源形势的研究

新亚欧大陆桥,是又一条连接亚欧大陆的“黄金通道”。陆桥的开通,给河南城市群的崛起和城乡产业经济的发展带来了契机。作为经济可持续发展限制因素之一的地下水资源,在陆桥（河南段）经济带范围内,能否满足沿线经济对地下水的需求？研究结论是：地下水形势不容乐观,潜力尚有８７×１０８ｍ３／ａ,同时还存在超采量３８８×１０８ｍ３／ａ,城乡开发地下水强度不一,已引发多种环境地质问题,对陆桥（河南段）经济带的发展构成了严重威胁。为缓和陆桥（河南段）沿线用水矛盾,必须遵循“因地制宜,量水为出,适度开发,统一规划”的原则,在开源、节流、管理上做好用水文章,充分发挥地下水资源的整体效益,实现陆桥（河南段）经济带地下水的可持续开发利用。     

基于GIS技术的三江平原热量资源评价

基于GIS技术,使用黑龙江省气象观测站和农垦、森工系统观测站的气温资料,以及数字高程模型(DEM)资料,运用趋势面分析法和线性内插法得到三江平原栅格化的热量资源数据。分析表明,三江平原纬度和高度因子对各项热量指标分布均有影响,经度因子主要影响年平均气温、4月平均气温、7月平均气温、≥0℃积温和≥10℃积温;佳木斯西部、双鸭山西部、鸡西大部热量资源较丰富,而青黑山、完达山、老爷岭和太平岭等地区热量资源相对较差。分析结果为合理开发利用三江平原热量资源提供了依据。     

黄河上游地区气候变化及其对黄河水资源的影响

通过对1961年以来黄河上游地区气候变化的分析,发现黄河源区进入80年代中后期以后,年平均气温上升趋势非常明显,特别是1998年的年平均气温竟达到-2.1℃,是40年来年平均气温最高的一年;进入90年代,春季和夏季温度急剧回升.黄河上游地区年平均降水量及秋季降水量无明显的变化趋势,且其年际间的波动趋于缓和;冬季(12～2月)和春季(3～5月)降水量的变化趋势呈现出逐年增多的趋势;夏季(6～8月)降水量变化趋势却表现出显著的减少趋势.同时,分析了38年黄河上游径流量及其与流域降水、气温的关系,着重分析了干旱气候对黄河水资源的影响.结果表明,黄河上游地区水资源呈减少趋势,其减少趋势进入90年代后尤为明显.这一变化趋势与黄河上游地区夏季降水量变化趋势有着一致性,说明汛期降水量的减少是黄河上游流量减少的最直接的气候因子.     

基于PS-DR-DP理论模型的区域资源环境承载力综合评价（英文）

The concepts of regional resources and environmental carrying capacity are important aspects of both academic inquiry and government policy. Although notable results have been achieved in terms of evaluating both these variables, most researchers have utilized a traditional analytical method that incorporates the "pressure-state-response" model. A new approach is proposed in this study for the comprehensive evaluation of regional resources and environmental carrying capacity; applying a "pressure-support", "destructiveness-resilience", and "degradation-promotion"("PS-DR-DP") hexagon interaction theoretical model, we divided carrying capacity into these three pairs of interactive forces which correspond with resource supporting ability, environmental capacity, and risk-disaster resisting ability, respectively. Negative carrying capacity load in this context was defined to include pressure, destructiveness, and degradation, while support, resilience, and promotion comprised positive attributes. The status of regional carrying capacity was then determined via the ratio between positive and negative contribution values, expressed in terms of changes in both hexagonal shape and area that result from interactive forces. In order to test our "PS-DR-DP" theory-based model, we carried out a further empirical study on Beijing over the period between 2010 and 2015. Analytical results also revealed that the city is now close to attaining a perfect state for both resources and environmental carrying capacity; the latter state in Beijing increased from 1.0143 to 1.1411 between 2010 and 2015, an improved carrying capacity despite the fact that population increased by two million. The average contribution value also reached 0.7025 in 2015, indicating that the city approached an optimal loading threshold at this time but still had space for additional carrying capacity. The findings of our analysis provide theoretical support to enable the city of Beijing to control population levels below 23 million by 2020.

黑龙江双鸭山地区白钨矿勘查开发的思考

双鸭山铁矿早已被开发利用,而钨矿却被忽略。文章通过对该成矿区典型矿床的地质特征,矿物学特征研究认为,铁矿、钨矿往往处于同一成矿区段,相伴产出,因此在该地区应加强钨矿的勘查力度。在矿床开发方面应统一布局,合理开发利用,达到资源利用最大化。
