Radioactive markers are useful in dating lead （Pb） deposition patterns from industrialization in sedimentary archives. As a well-known natural reserve in the world, yancheng coastal wetland in Jiangsu Province is one of areas most sensitive to global sea level change and is located in the most developed and polluted region of China. Two cores were collected in yancheng wetland in October 2013 and dated using 210pb and 137Cs radiometric techniques. Sediments in both cores were sectioned into depth bands and examined systematically for dry bulk density, water content, magnetic susceptibility and grain-size. Multiple elements including Pb were also measured using inductively coupled plasma systems. Unsupported 21~Pb activities decreased with depth in both of the two cores, and 21~pb chronologies were established （covering 150 years） using the constant rate of supply （CRS） model. The measured Pb contents ranged from 14.97 mg/kg to 29.40 mg/kg with average values of 17.17-22.79 mg/kg, and the Pb fluxes ranged from 41.70 mg/（m2·yr） to 172.70 mg/（m2·yr） with averages of 95.59-123.41 mg/（m2·yr）. Temporal variations of Pb flux, enrichment factors and Pb isotopes show a gradual and continuous increase over time and clearly reflect increased emissions from anthropogenic activities in the region. The Pb isotopic compositions show that most of Pb deposition in yancheng wetland is input from natural sources by water flows and has the same levels of Pb as in the surface sediment of the Yangtze River and the Pacific mineral aerosol. We also stress the anthropogenic Pb contribution in Yangcheng wetland sediment and the reason of our Pb isotopes not showing anthropogenic signature is likely the insta- bility of anthropogenic Pb in high Fe/Mn oxide conditions. Therefore, more attention should be paid to current local pollution problems, and society should take action to seek a balance between economic development and environmental protection.

[Objective] The reseamh aimed to contrast and analyze CG activity rules in Lianyungang and yancheng. [Method] By using lightning location data, basic characteristics of lightning activities in Lianyungang and yancheng both located at the eastem coast of Jiangsu were analyzed and contrasted. [Result] CG characteristics in Uanyungang and yancheng were same, and negative CG was dominant. Monthly change activity rule of CG basically presented single-peak distribution, and peak value appeared in August. Monthly change of the lightning was drastic, and high- occurrence period was both in summer. Daily change trend of CG in the two sites was consistent. High-occurrence period of the lightning was in af- temoon and early morning, and occurrence frequency of the lightning in the morning was less. Spatial distribution of CG in Lianyungang and yancheng was very uneven. Lightning activity in Lianyungang mainly concentrated in northwest and southeast areas of Donghai County and western area of Guannan County. Especially in Donghai County, it was the area where lightning strike density was the maximum. Lightning strike activity in Yanchang was more concentrated, and mainly concentrated in the west, namely near Jiangying Town and Louwang Town. Distribution characteris- tics of CG intensities in the two sites were same. Waveform changes of the positive CG in the two sites were slower than that of the negative CG, and current intensity concentrated from ＋ 20 to ~ 50 kA. [ Conclusion ] By contrasting and analyzing lightning activity rules in Lianyungang and Yanchang, we could share and complement data in the two cities better, and serve for routine lightning prevention and early-warning better.

Suaeda salsa is an important local species in the intertidal beach of the Western Pacific coast. However,under the artificial cofferdam and Spartina alterniflora expansion,Suaeda marsh has degraded seriously. Therefore,using yancheng Nature Reserve as a case study area,taking ETM+images in 2000,2006 and 2011 as the basic data sources,we revealed the evolution characteristics of Salsa marsh which was impacted. The research results are as follows. From 2000 to 2011,Salsa marsh area in the artificial area tempestuously degraded,decreasing by 87. 158%,more than 22% than those in the natural area. The landscape was fragmentized. Landscape polymerization degree index dropped from 95. 780 to 65. 455,more than 16% than those in the natural area. The mean patch area fell down to 21. 429 ha from 389. 333 ha,more than 11% that in the natural area. Compared to the steady change in natural conditions,the area was reduced by 118. 167 ha/a from 2000 to 2006,while during 2006-2011,it was only 51. 500 ha/a in artificial area. As for spatial change of landscape,in artificial area,the Salsa marsh centroid moved forward to the southeast with 666. 350 m,but that in natural area moved forward to the north with 1 042. 710 m from 2000 to 2006. From 2006 to 2011,the centroid moved forward to east and north respectively. Artificial cofferdam transformed the area into freshwater ecosystem,and meanwhile the freshwater was beneficial to Reed marsh. During 2000 to 2006,in the artificial area,539 ha Salsa marsh controlled by cofferdam transferred into reed marsh and aquaculture ponds,of which the transformation rate was nearly 4% higher than that in natural area. From 2006 to 2011,178 ha Salsa marsh was transferred into reed marsh,the transformation rate was 20% higher than that in natural area. With rapid spreading and strong competition of Spartina species,the coastal wetland has formed the pattern of " Salsa – Spartina marshes". From 2000 to 2006,in artificial area,15. 24% of Salsa marsh was t

Improved understanding of the spatial dynamics of invasive plant species is critical for effective land management and control of future invasion. The yancheng National Nature Reserve (YNNR), an internationally important wetland, has the largest distribution of alien Spartina alterniflora in China. This alien plant was intentionally introduced for erosion prevention and dike protection in China. However, it became an aggressive competitor with native salt marsh plants in the coastal regions in China. High resolution imagery, SPOT-5, was used to map plant communities including invasive species in the south core zone of YNNR with the natural ecosystem of salt marshes in 2003, 2005 and 2008. The fuzzy set assessment method significantly improved the classification accuracies over the conventional error matrix, i.e., from 73.8%, 73.5% and 81.4% to 91.5%, 91.6% and 93.4% in 2003, 2005 and 2008, respectively. It shows a great potential for mapping invasive plant species. Phragmites australis and S. alterniflora were the most accurately mapped classes, and sparse and dense Suaeda glauca were the least accurately mapped. From 2003 to 2008, S. alterniflora increased 28.8% from 1664.1 to 2142.6 ha in area size, and more than 2.5 times from 742 to 2608 patches. The highest increase in patch number occurred within the interval between 2001 and 3000 m from the eastern baseline. This increase was dominated by small patches with area less than 200 m2. During the study period, the mean spread width was 405 ± 80.7 m in the original large patch of area over 200 ha. The eastward/seaward spread was distinctively larger than the westward/landward. The results enhance the understanding of alien plant’s invasion patterns and help improve conservation efforts.
