Using the techniques of \"3S\" and landscape ecology, based on 1991 and 2009 Landast TM remote sensing image, integrating with the change of water modeling、transform matrix、the shift of gravity centers and landscape pattern analysis software Fragstats3.3, the water dynamic changes of structure and spatial characteristics in Wuhan city are studied during the 19 years. All these provided some reference for reasonable utilization and protection water and realization the regional sustainable development. The main results show that: From 1991 to 2009 ,under the influence of population, socio-economic, policy and so on, the area of water has a sharp drop, the reduce of water is significant different in every administrative region, the change of water is particular in East-Western lake and Caidian, the conversion between farmland and water and water to construction land are obvious, the gravity centers of water have shifted obviously in Caidian and Xinzhou, the feature of landscape elements is significant different and the water area will continue to decrease largely.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115588031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicated: (1) only the content of Cd exceeded background levels of soils, which was 9.53 times as GradeⅡof GB15618. There is obvious spatial difference among heavy metals and the main contamination sources may be were external inputs. The frequency distribution and distribution the corresponding curves of the four kinds of heavy metals were not a normally distribution. (2) There are higher accumulations of heavy metals such as Cd, Pb, Zn and As in cropland soils. On the basis of the value of Integrated Pollution Index (PIN), was 7.01 which showed the degree of the heavy metal contamination the severe pollution in study area. Cd was the major one and severe pollution, which value of Single-factor Index (Pi) was 9.53; while the other heavy metals three were no pollution. (3) The content of heavy metals had differences in elevation. The riverside sample transect was polluted seriously, while the hill one was affected lightly. The content of heavy metals had the same trends but differed in kinds of heavy metals.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124338255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to analyze the effects of land use pattern on carbon emission, using data from Panyu District of Guangzhou City, the authors calculated the carbon emission which is influenced by different land use patterns. The results indicated that carbon emission is significantly diverse according to different land use patterns, in which the construction land and cultivated land are the two main carbon sources. It was found that carbon emissions were increasing by 16.6% during 1990-2005. Furthermore, two indexes that could better reflect carbon emission intensity were calculated. The carbon emission per unit area of land and carbon emission per unit area of construction land respectively showed a value of 15.29 t/hm2 and 86.23 t/hm2 in 2000. The land for construction was the largest carbon source, and the carbon emission per ha was increasing from 1990 to 2005. However, carbon sink maintained generally stable during this period. Finally, some suggestions on carbon emission reductions and fostering studies about low-carbon economy in Panyu District were given.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116265414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that as the intensity of human activities gradually strengthened in the past fifteen years, the integral structure of wetland types in this district had been varied greatly. The area and the patches number of the natural wetland decreased dramatically, while that of constructed wetland area increased incredibly. It was evident that the wetland landscape had transformed from natural to artificial. The change of each landscape index demonstrated that in the guidance of feedback information of hydrology and water resources availability and use risk, human economic activities not only directly changed the wetlands area but also changed the wetlands spatial pattern by the economic utilization of the wetlands in the past 15 years. The fragmentation degree aggravated and the wetlands went into a state of relatively uneven distribution, which further explained the spatial pattern that the area and the proportion of the natural wetlands reduced and the constructed wetlands tended to be dominant in Daqing River downstream.","PeriodicalId":412601,"journal":{"name":"2010 International Conference on Multimedia Technology","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122144949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
