为跟踪世界科技的最新进展,解决中国快速发展过程中所面临的关键性和突出性重大问题,中国政府开展了一系列重大科技专项计划,如科技支撑计划等。气候变化、地表过程、土地利用、自然灾害是近年来人文一经济地理学者参与最广、研究最深的领域,在地表过程的人文驱动机制、资源环境承载能力评价等方面取得了重大进展和突破,为政府编制规划、开展环境外交等提供了科学依据。本文分析了上述研究计划的基本概貌,以及人文一经济地理学者在其中承担的主要任务。从个人终端消费导向的碳足迹研究、人文地理过程的系统动力学研究、土地利用重点问题咨询与决策、灾区资源环境承载能力评价等方面总结了人文一经济地理学在其中做出的主要贡献和社会影响。  相似文献

徐祥明  何毓蓉 《山地学报》2011,29(6)

土壤微形态学从20世纪30年代发展至今,取得了很大的进步,并广泛应用于土壤学各个领域,解决了很多土壤学问题.越来越多的学者应用土壤微形态学方法进行其他学科领域的研究,并取得了很好的结果.与国内比较,国外土壤微形态学各方面的发展都更早、更为成熟.从国外土壤微形态学的发展简况以及土壤微形态学在其他学科领域的应用研究最新进展进行报道,如土壤发生与分类、土壤肥力与土壤环境、考古与第四纪等,以期对国外土壤微形态学的研究成果做一初步的小结和为国内土壤微形态学的发展提供一定的参考借鉴.  相似文献   

Validation of WRF model on simulating forcing data for Heihe River Basin     

XiaoDuo Pan  Xin Li 《寒旱区科学》2011,3(4):0344-0357

The research of coupling WRF (Weather Research and Forecasting Model) with a land surface model is enhanced to explore the interaction of the atmosphere and land surface; however, regional applicability of WRF model is questioned. In order to do the validation of WRF model on simulating forcing data for the Heihe River Basin, daily meteorological observation data from 15 stations of CMA (China Meteorological Administration) and hourly meteorological observation data from seven sites of WATER (Watershed Airborne Telemetry Experimental Research) are used to compare with WRF simulations, with a time range of a whole year for 2008. Results show that the average MBE (Mean Bias Error) of daily 2-m surface temperature, surface pressure, 2-m relative humidity and 10-m wind speed were ?0.19 °C, ?4.49 hPa, 4.08% and 0.92 m/s, the average RMSE (Root Mean Square Error) of them were 2.11 °C, 5.37 hPa, 9.55% and 1.73 m/s, and the average R (correlation coefficient) of them were 0.99, 0.98, 0.80 and 0.55, respectively. The average MBE of hourly 2-m surface temperature, surface pressure, 2-m relative humidity, 10-m wind speed, downward shortwave radiation and downward longwave were ?0.16 °C, ?6.62 hPa, ?5.14%, 0.26 m/s, 33.0 W/m² and ?6.44 W/m², the average RMSE of them were 2.62 °C, 17.10 hPa, 20.71%, 2.46 m/s, 152.9 W/m² and 53.5 W/m², and the average R of them were 0.96, 0.97, 0.70, 0.26, 0.91 and 0.60, respectively. Thus, the following conclusions were obtained: (1) regardless of daily or hourly validation, WRF model simulations of 2-m surface temperature, surface pressure and relative humidity are more reliable, especially for 2-m surface air temperature and surface pressure, the values of MBE were small and R were more than 0.96; (2) the WRF simulating downward shortwave radiation was relatively good, the average R between WRF simulation and hourly observation data was above 0.9, and the average R of downward longwave radiation was 0.6; (3) both wind speed and rainfall simulated from WRF model did not agree well with observation data.  相似文献   

On the opening-up and development of shanghai’s pudong new area     

Wanzhong Yang 《中国地理科学(英文版)》1993,3(4):348-356

In the development of Pudong, a strategic idea and goal ought to be fully realized, that is: with the development of Pudong as a lead, to further open up the cities along the Changjiang (Yangtze) River, build Shanghai into an international center for economy, finance and trade, thus to spark a new economic take- off in the Changjiang River Delta and the whole Changjiang River Basin. To develop Pudong, the infrastructure construction must be developed first; and the development of primary, secondary and teriary industries must be well coordinated. At present, the stress should be laid on tertiary sectors like finance, foreign trade, comerce, real estate, far-ocean transport, post and telecommunication, information and travelling service and so on. In the secondary industry, export processing and high and new technological industries should be put first, while the original raw-material industry should be improved in processing depth. As to the primary industry, a metropolitan suburban agriculture should be established. In spatial distribution, the present extension has been eastward along the Huangpu River axis. By the end of this century, five districts: Waigaoqiao-Gaoqiao, Qingningsi-Jinqiao, Lujiazui-Huamu, Zhoujiadu-Liuli and Beicai-Zhangjiang, will be developed. Meanwhile, it must be well coordinated between developing Pudong and reforming Puxi.  相似文献
