Research on changes of land use in natural reserves is an critical issue and discussion of land use policies relevant to them is needed for their preservation in face of pressures of local socio-economic *** study examined Tianjin Palaeocoast and Wetland National Natural Reserve(TJPW) and reviewed its development processes,status of adjustments and evolutionary *** use/cover change(LUCC),driving forces,adjustment schems,and land use policy changes were also investigated. Land use changes were studied by supervised classification of Landsat TM remote sensing images of 1988,1998,and 2008,*** economic development is the main driving force of *** such,it is critical to lay out a scientific,integrated development plan for adjustment that pays more attention to changes in natural reserve land properties and establishes ecological protection *** addition,the ecological integrity of natural reserves needs to be preserved and sustained instead of randomly modifying their boundaries to meet the demand of key infrastructure ***,the results described in the study provides a detailed reference model that can lead to adopt boudary adjustment strategy to balance coastal wetland protection and a sustainable development of resource’s management.

反映地表粗糙状况特征量的地表粗糙度是非线性的 ,可以用分形去刻划。雷达遥感具有对地表粗糙度敏感的特性 ,故利用美国航天飞机 3号 ( SIR- C/ X- SAR)雷达遥感数据 ,选择干燥的内蒙古额济纳旗东北区作为雷达回波与地表粗糙度分形测量研究实验区。实测的计算结果表明 ,在 2～ 10 cm无标度区间 ,此处的戈壁面为具有分形特征的粗糙地形面 ,从雷达遥感的后向散射系数分析表明 ,该区对 C波段 (λ =5 .3 cm) HH极化回波贡献非常强烈 ,其原因是 2～ 10 cm区间尺度正好含盖航天飞机雷达波 C波段长度 ,而小于 L波段 (λ=2 3 .5 cm )长度 ,此结论实证了戈壁地貌表面在一定区间具有分形的特征 ,并可以为雷达遥感某一波段所强烈表现出来 ,这将为借助分数维对图像处理、地物分类以及表面侵蚀定量刻划提供重要的科学依据。

作者： Peng Zhang and Xueping Zhang﹡ School of geography Science Harbin normal university Key Laboratory of remote sensing Monitoring of Geographic Environment college of Heilongjiang Province Harbin Heilongjiang Province chinaLei Wang School of Architecture and Civil Engineering Heilongjiang Institute of Science and Technology Harbin Heilongjiang Province china

Soil health risk assessment is used to formulate soil environmental quality standard, and it is a new environment management method. Case study in urban center of Harbin, rural-urban fringe zone,primary toll gate in Songbei high way and Harbin Aircraft Manufacturing Company, full-scale study of Harbin soil lead pollution situation was made by the method the literature material and field survey, we calculated the lead exposure for the children from the soil in Harbin using biological dynamic model of MARCUS, and made the risk assessment of MMR incidence. The results showed that there was different of the levels of lead pollution in different function zones of Harbin, the both sides of road﹥around of factory﹥the banks of Songhua River﹥ suburban farmland﹥residential areas. The content of lead obviously accumulated in 20 meters on both sides of the road, and the content of lead in industrial zone was of great difference for human factors, without obvious rule. Furthermore, the lead exposure of children aged from 0 to 6 from the soil in Harbin was between 7.96×10-5 and 1.98×10-4mg/d, and the health risk of MMR was 20.307 per 1,000.

Cenozoic sediments in the foreland basin——Jiuquan Basin in west Hexi Corridor recorded tectonic uplift information of the Qilian Mountains. High resolution paleomagnetic dating of the Laojunmiao （LJM） section across the central LJM anticline in the southern Jiuquan Basin reveals ages of the Getanggou Member, Niugetao Member in the Shulehe Formation, the Yumen Conglomerate, Jiuquan Conglomerate and Gobi Formation at >13―8.3 Ma, 8.3―4.9 Ma, 3.66― 0.93 Ma, 0.84―0.14 Ma and 0.14―0 Ma, respectively. Sedimentary evolution study suggests that the Qilian Mountains should begin to rise gradually since8―6.6 Ma, accompanied by sedimentary environments changing from lacustrine mudstones-sandstones to alluvial conglom- erates. Rapid uplift of the Qilian Mountains began at3.66 Ma, followed by a series of stepwise or intermittent intensive uplifts at about 4 Ma and 0.14 Ma, which finally resulted in the present high Qilian Mountains.
