山东沿海地区百年一遇潮位淹没影响的耕地脆弱性评价

Evaluation on the cultivated land vulnerability of Shandong coastal areas under the flooding influence of 100-year tide level

    摘要
  • 摘要: 山东沿海七市耕地面积占全省耕地面积的37.91%，农业产值占全省的41.12%。由于经常受风暴潮的影响，农业损失巨大。沿海耕地分布区地势较为低平，潮水灌入农田，使当季农作物损失率为100%，同时又改变土壤性质，影响下一季农作物的生长，而防潮堤标准低且达标率不高，对百年一遇风暴潮抵抗力较弱。因此，对山东沿海地区耕地脆弱性评价有利于防灾减灾。本文利用landsat ETM、数字高程模型和地表覆盖数据，运用GIS系统评价山东沿海地区百年一遇潮位淹没影响的耕地脆弱性。将脆弱程度划分为七级，研究结果如下：极高脆弱性的地区是垦利县、东营区；很高脆弱性的地区有河口区、昌邑县、广饶县与寒亭区；高脆弱性的地区是城阳区、崂山区与寿光市；中脆弱区的地区有莱州市、平度市、垦利县与东营区；低脆弱的地区有岚山区、牟平市、文登市、荣成市、即墨市、胶州市、无棣县、东港区、龙口市、海阳市、河口区、沾化县与黄岛区；很低脆弱的地区有蓬莱市、环翠区、利津、芝罘区、崂山区、乳山市与城阳区；极低脆弱的地区有福山区、莱山区与招远市。其中垦利县、东营区、寒亭区、广饶县、昌邑县与寿光市的脆弱性是由于百年一遇潮位较高，淹没耕地比值大；河口区脆弱性是由于当地淹没耕地比值大。

     

    Abstract: the cultivated land area of the seven cities along the coast of Shandong accountes for 37.91% of the total cultivated land in the province.The agricultural output value accountes for 41.12% of the province.Because of the frequent storm surge, the agricultural loss was huge.The altitude of coastal cultivated land area is relatively low.When the tidal water easily run into the cultivate, the crop loss rate ofen is 100% in the current season.At the same time, tidal water changes the soil properties and affects the crop growth of the next season.The anti-tidal standard of the dyke and the compliance rate are low, they cannot against the 100-year storm surge.Therefore, it is conducive to mitigate disaster that we evaluate the vulnerability of cultivated land in the coastal areas of Shandong province.Apply landsat ETM, digital elevation model, surface coverage data and GIS system, this paper evaluated the vulnerability of cultivated land affected by 100-year tide in the coastal area of Shandong province.The vulnerability is divided into seven levels.Research result is as follows:The extremely high vulnerable are Kenli county and Dongying district; the very high vulnerable are Hekou district, Changyi county, Guangrao county and Hanting district; the high vulnerable areas are Chengyang district, Laoshan district and Shouguang city; The medium vulnerable are Laizhou city, Pingdu city, Kenli county and Dongying district; the low vulnerable are Lanshan district, Mugping city, Wendeng city, Rongcheng city, Jimo city, Jiaozhou city, Wudi county, Donggang district, Longkou city, Haiyang city, Hekou district, Zhanhua county and Huangdao district; the very low vulnerable are Penglai city, Huancui district, Lijin county, Zhifu district, Laoshan district, Rushan city and Chengyang district; the extremely low vulnerable are Fushan district, Laishan district and Zhaoyuan city.The vulnerable is caused by the 100-year tide level and the large ratio of inundated cultivated land in Kenli county, Dongying district, Hanting district, Guangrao county, Changyi county and Shouguang.The vulnerable is caused by the large ratio of inundated cultivated land in the Hekou district.
