The coastal lowlands, or said the the the coastal areas of the low-elevation (Low elevation coastal zones, LECZ) is to the above sea level height of less than a 10m of the coastal continuous Strip. Coastal lowland is both a densely populated, the economic is well-developed an important region, but also is the the sensitive fragile belt of the the sea - the the ecological of LAND INTERACTION AND ITS, natural disasters multi-hair, the losses caused by disasters is serious. The in order to ArcGIS, the of this article as the main data analysis of platform, based on the SRTM 90m DEM, the the world's population raster data (GPWv3), the the 1:100 million Chinese administrative divisions and the the Hotspots disasters data, determine the a lowland the of the the scope of with the space of of the China's coastal distribution of, the analysis of of a China coastal of the population time of the lowland distribution of and the of the population of the natural disasters exposure, to obtain a are as follows the results of: (1) the the the the the total area of ??of of the of China's coastal lowlands for the 161,491,819,056 m2, accounting for 1.7% of the total land areas of the country. The the National there are are 14-level Administrative Region (SAR) in, more than 350 L2 Administrative Region (SAR) (the county or city level) covered with coastal lowlands. Coastal lowlands the largest area of ??is, Jiangsu Province,, amounting to 63,749,258,407 m2, accounting for for 63.16% of of the area of ??the province, an accounted for of 39.5% of the area of ??of of the the national sea lowland; The area of ??is the smallest is Macau, is 9,124,350 m2, but you want to to accounted for for for 35.68% of of the Macau's total area of. From the point of view the the proportion of of's share of the the level Administrative Region (SAR) area of, the the largest the the of the coastal lowland of the proportion of of of Shanghai and Tianjin, respectively, accounted for 97.91% and 82.79% of the two municipalities directly under the Central Government area of ??of the of, the the proportion of is the smallest is Guangxi Zhuang Autonomous Region, an of only of 0.41%. (2) according to the to the the the in 2000 the world's population raster data come to that the, the the number of the China coastal lowland population for the 119 498 023 people, accounting for about 22.51% of the the number of of of the coastal the level Administrative Region (SAR) population, accounting for 9.3% of the total the the the total data of the the of the of China's population, the the the area of ??of the coastal lowlands accounted for only for 1.7% of the area of ??of of Homeland, but the population the number of has accounted for for 9.3% of the the the the total data of the the of the of China's population, Description that the coastal lowlands is the our country's important life of the population and economic activities District,. The of the provinces with the a maximum of the coastal lowland population the number of for the, Jiangsu Province,, 46,227,246 people, and Secondly for the, Guangdong Province,, 16,728,791 people; coastal lowlands level Administrative Region (SAR) population the number of accounted for the coastal level Administrative Region (SAR) population the proportion of on the Shanghai highest amounted to 99.50%, and the was followed by the is Tianjin amounted to 91.77 %, the the the number of coastal lowland level Administrative Region (SAR) population accounted for that the the The the the proportion of the population of the the coastal level Administrative Region (SAR) is the smallest of the which is the Guangxi Zhuang Autonomous Region, of only 0.64%. (3) the Most of the the the of the coastal lowland of population of of the level Administrative Region (SAR) over time change constantly increase the. The most significantly is the the the largest of the years segment of in of the, Guangdong Province,, population growth 1990-1995 years, a growth rate for the 40.52%. Are subsequently the the the the growth of speed of of the every 5 years gradually slow down the for the 20.64%, 19.32%, 17.76%, 12.71%, but still higher than the the the growth rate of its provinces and cities in of other the Mainland coastal. The coastal lowlands population accounted for that the the proportion of first-order Administrative Region (SAR) population In addition to Hebei Province, Tianjin, the Jiangsu outside the province, the overall the growing. The (4) tropical cyclone in the the the the the occurrence of frequency of of the China coastal lowlands, in order to to the the the of the coastal lowland of the highest of south of the Zhejiang, by the the the Yangtze River Delta to the the coastal lowlands of the the northern side of to quickly lower the. The the the provinces of to the south of, the Zhejiang, autonomous regions, and the frequency of occurrence of by the the of the coastal lowland of of the a Special Administrative Region of tropical cyclone is very the median an average of for the the the 8.0 and above, provinces, or municipality directly under the Central Government the north of the Jiangsu is then the in the below 4.0. The the coastal lowlands risk of death in the the south of of the Yangtze River was significantly higher than that the the coastal lowlands in the the north of of the Yangtze River. But the the the risk of death of the the coastal lowland of the of the Hong Kong and the a Special Administrative Region of of Macau for the 0; and the the the the the risk of death of of the, Jiangsu Province, coastal lowlands want to higher than that of Fujian and other multiple the south of of the level Administrative Region (SAR) in in the the Yangtze River, achieve the 6.0. The Generally in terms of, the the tropical the cyclone occurred in the of the total economic loss of risk and the economic losses the proportion of risk two indicators are indicative of the the and low in the north of high in the south and of the the distribution of characteristics of. (5) our country the the flood of the eastern part of coastal lowland occurrence of frequency, the Generally in terms of, the the the Yangtze River Delta, of the the between the of the region the highest in in the the the Pearl River Delta region and its, risk Level in the around 8.0 more than. The Jiangsu, Shanghai, Zhejiang, Taiwan, Guangdong the of the coastal lowland of flood of the risk of death the highest, in the the the around 8.0. Hong Kong, Macao Special Administrative Region (SAR) are all 0; the point of view the risk of from the the the economic losses of of the coastal lowland flood, the, the Macao Special Administrative Region (SAR) for the the the lowest, of only 2.0. The the the's economic the risk of loss of of the Jiangsu, Shanghai, Zhejiang, Taiwan, and Guangdong coastal lowlands is is were very high, in order to the left and right of 9.0. The risk of economic losses the proportion of, Guangdong Province, the highest, for the 9.0, other provinces and cities the a Special Administrative Region of of the, autonomous regions, mostly in the 5.0-7.0. (6) the tropical cyclone of the the coastal lowlands in the south of Shanghai high occurrence of to of the population of the frequency District, a significant proportion of, Shanghai, and Zhejiang is greater than 70% of the, the Further south of the Fujian, Guangdong and, etc. provinces, autonomous regions, and a Special Administrative Region of greater than 95% in both. While the Jiangsu north of, high occurrence of the the the proportion of of the population of the frequency District, is is then the a lower, in particular is Shandong and Tianjin low-occurrence of to the the frequency District, of the population than the the of Health all reached or close to 100%. Jiangsu north of, the of the population of the coastal lowlands is mainly distributed in the the flood low-frequency of occurrence District,. Shanghai south of, In addition to the the Taiwan and Hainan, the rest of level Administrative Region (SAR) coastal lowlands flood high occurrence of the of the population of the frequency District, the proportion of a great, and even close to or to reach 100%.
