武钢工业区绿地景观格局分析及综合评价

城市绿地作为工业区生态系统中主要的自然成分和初级生产者,在改善环境质量、调节生态平衡、维持生态安全上具有不可替代的作用。近年来,城市绿地景观生态研究虽然得到普遍关注,但现有的研究多倾向于一般空间格局分析,针对不同功能区的绿地景观生态综合比较评价研究却少见报道。以武钢工业区为例,选用IKONOS为主要信息源,结合外业调查,建立工业区绿地地理信息系统,以景观生态学理论为指导,从物种丰富度、群落结构、绿地类型斑块特征、景观异质性等方面进行了武钢工业区绿地景观生态学分析,并运用主成分分析法,对不同功能区绿地景观生态学作了综合评价,为区域景观生态综合评价提供一定的参考。研究结果表明：工业区中普遍运用的是抗性较强的树种,种类较丰富,其中物种数量为7～8的斑块出现频率及面积均最高。武钢绿化覆盖率为30．58％,绿地破碎,主要由中小型绿地斑块组成,附属绿地是工业区绿化主体。公园绿地物种搭配最为丰富,绿化质量较高,其它绿地空间呈团聚状态分布,防护绿地形态格局比较简单,生产绿地分离度最大(0．718)。不同区域绿地景观格局表现差异显着,生活区绿地斑块规模普遍较大,绿化覆盖率高(43．27％),景观多样性高(3．39);主厂区绿地破碎度为1．3246,物种丰富度低(0．8941);工业港绿地物种丰富多样(1．1765),各景观格局指数居中。通过主成分分析,利用主成分与贡献率乘积的累积值,对不同区域绿地进行景观生态学综合评价,将评价指标综合为景观格局及物种多样性2项指标,由于主厂区绿地破碎,覆盖率低,分布不合理,物种单一,生活区普遍较好,最后得出生活区绿地景观生态最优,工业港次之,主厂区最差。该方法为绿地景观生态评价指标选择提供了一定的参考价值,为工业区绿地系统的景观结构优化提供依据。

Combination of Pre-Treatment DWI-Signal Intensity and S-1 Treatment: A Predictor of Survival in Patients with Locally Advanced Pancreatic Cancer Receiving Stereotactic Body Radiation Therapy and Sequential S-1

OBJECTIVE: To identify whether the combination of pre-treatment radiological and clinical factors can predict the overall survival (OS) in patients with locally advanced pancreatic cancer (LAPC) treated with stereotactic body radiation and sequential S-1 (a prodrug of 5-FU combined with two modulators) therapy with improved accuracy compared with that of established clinical and radiologic risk models. METHODS: Patients admitted with LAPC underwent diffusion weighted imaging (DWI) scan at 3.0-T (b = 600 s/mm²). The mean signal intensity (SI_b = 600) of region-of-interest (ROI) was measured. The Log-rank test was done for tumor location, biliary stent, S-1, and other treatments and the Cox regression analysis was done to identify independent prognostic factors for OS. Prediction error curves (PEC) were used to assess potential errors in prediction of survival. The accuracy of prediction was evaluated by Integrated Brier Score (IBS) and C index. RESULTS: 41 patients were included in this study. The median OS was 11.7 months (2.8-23.23 months). The 1-year OS was 46%. Multivariate analysis showed that pre-treatment SI_b = 600 value and administration of S-1 were independent predictors for OS. The performance of pre-treatment SI_b = 600 and S-1 treatment in combination was better than that of SI_b = 600 or S-1 treatment alone. CONCLUSION: The combination of pre-treatment SI_b = 600 and S-1 treatment could predict the OS in patients with LAPC undergoing SBRT and sequential S-1 therapy with improved accuracy compared with that of established clinical and radiologic risk models.

以宁夏自治区红寺堡区为例,以1995年、2000年、2005、2010年和2015年5期遥感影像为数据源,综合运用景观格局指数、生态风险指数、空间分析法以及地理探测器等多种研究方法,研究了移民安置区生态风险时空特征。结果表明:1995—2015年研究区景观格局发生了较大的变化,草地面积减少了2.97×10~4hm~2,耕地、林地、建设用地分别增加了1.90×10~4hm~2,0.42×10~4hm~2和0.43×10~4hm~2;在研究期间景观整体斑块数不断增加,其景观整体破碎度随之变大;研究区生态风险主要以较低风险和中风险为主,其中建设用地、沙地和未利用地生态风险值较高,在研究期间生态风险平均值由0.166降低至0.154,研究区生态风险值呈降低趋势。通过地理探测器诊断得出景观斑块数、景观破碎度、景观优势度、景观损失度、斑块密度等因素是安置区生态风险的主要影响因素。

Odense Pilot River Basin: implementation of the EU Water Framework Directive in a shallow eutrophic estuary (Odense Fjord,Denmark) and its upstream catchment

Implementation of the EU Water Framework Directive (WFD) is a huge environmental management challenge for Europe, demanding an integrated sustainable approach to water management and a common objective of obtaining ‘good status’ for all water bodies before 2015. The main task is the preparation of a river basin management plan for each of the 96 European river basin districts before the end of 2009. In Odense River Basin (island of Fyn, Denmark), one of 14 appointed European Pilot River Basins, the implementation of the WFD has been developed and tested in practice. Reference conditions and ecological status classification for Odense Fjord, based on eelgrass (Zostera marina) depth limit and nutrient concentrations, have been drawn up through a combination of historical data and modelling tools. A subsequent quantitative linking of pressures and impact, in casu between land-based nitrogen (N) loading of the fjord and resulting nutrient concentrations and eelgrass appearance, provided an estimate of the needed nitrogen load reduction of the fjord. This amounted to approx. 1,200 tonnes N per year (an annual load reduction of ca. 11 kg N ha^?1 of catchment area or ca. 19.5 g N m^?2 of fjord surface)—a load reduction of ca. 60% from the present level—to obtain at least ‘good’ ecological status sensu WFD. It is presently not possible to quantify a target load for phosphorus (P) in relation to marine environmental objectives. An economically feasible programme of measures to obtain ‘good’ status in all surface water and groundwater bodies in Odense River Basin, using an integrated cost-effectiveness analysis, showed that re-establishment of wetlands, catchcrops, and reduced fertilisation norms are the most effective measures if large reductions in N loads to the aquatic environment are to be achieved. The total socio-economic cost of implementing the WFD in the river basin amounts to about 13 million €/year, which will increase the expense for water services by only 0.5–0.6% of the total income and production value in the basin (15,650 million €/year). Investments to obtain the needed nitrogen load reductions from agriculture are thus economically feasible. Further, it is not an impossible task, either economically or technically, to reach the objectives of the WFD while still retaining the possibility of keeping a high agricultural production in the catchment (maintaining livestock production but decreasing crop production in the case of Odense River Basin). The future conditions in Odense Fjord will not only depend on the success in reducing the load from the river basin area, but will also be affected by the trend in the nutrient loss from the whole Baltic catchment area. The high growth rates in the new EU Member States thus pose an important challenge to water managers, and decoupling of economic growth from pressure on water bodies will be necessary. Finally, a number of challenges facing water managers around the Baltic and within the EU, namely preconditions required to successfully implement the WFD, are presented.
