京津冀大气污染传输通道区大气污染时空格局研究

客观理解京津冀大气污染传输通道城市（“2+26”城市）空气污染时空格局对于区域大气污染联合防治具有重要意义.本研究采用遥感数据反演的PM_2.5浓度产品，利用趋势分析法和重心分析法，揭示了京津冀城市大气污染传输通道区2000~2015年大气污染时空格局演化特征.结果表明：（1）区域PM_2.5平均浓度整体呈现出太行山脉区域较低，太行山脉以东较高的格局，城镇地区明显高于周边地区.（2）2000~2015年区域PM_2.5年均浓度总体呈增加趋势，主要表现在2000~2007年，呈显著增加趋势的面积占全区的88.48%，之后呈稳定状态.（3）区域PM_2.5污染重心位于衡水、邢台和德州3市交界处，区域北部大气污染较严重.本研究可为京津冀及周边地区大气污染防治政策制定和措施实施提供参考与支持.

复垦区景观异质性研究

景观生态学目前发展较为迅速，研究的领域也日渐广泛，不仅有理论的探讨，也有应用方面的研究，从研究领域来看，研究较多的还是农业景观，森林景观、自然保护区与国家公园。复垦区景观异质性的研究还较少见，本文就这一问题作一初步探讨。

Spatial variations in daily average CO2 concentrations above wetland surface of Xianghai National Nature Reserve, China

Horizontal and vertical variations of daily average CO2 concentration above the wetland surface were studied in Xianghai National Nature Reserve of China in August, 2000. The primary purpose was to study spatial distribution characteristics of CO2 concentration on the four levels of height(0.1 m, 0.6 m, 1.2 m and 2 m) and compare the differences of CO2 concentration under different land covers. Results showed that daily average CO2 concentration above wetland surface in Xianghai National Natural Reserve was lower than that above other wetlands in northeast China as well as the worldwide average, suggesting that Xianghai wetland absorbed CO2 in August and acted as“sink” of CO2. The horizontal variations on the four levels of height along the latitude were distinct, and had the changing tendency of“decreasing after increasing” with the increase of height. The areas with obvious variations were consistent on different levels of height,and those with the highest variations appeared above surface of shore, sloping field, Typha wetland and Phragmites wetland; the vertical variations were greatly different, with the higher variations in Phragmites wetland and Typha wetland, and the lands near the shore and the sloping field with the lower variations. Spatial variations of daily average CO2 concentrations above wet!and surface were affected by surface qualities and land covers.     

再生水为天津城市“解渴”

为了建设节约型社会，同时也为了解决本市供水资源紧张问题，天津市从现在开始加快建设再生水回用工程。中心城区再生水回用工程建设已全面铺开，共铺设再生水回用干管87.4km，实现再生水管道入户600万m^2；纪庄子日产5万m^2再生水工程已建成，环卫部门等企事业单位的冲厕、冲车、浇灌绿地、景观水体补水等均使用再生水。
