江苏省启东市属长江口沉积平原,南临长江,东、北濒临黄海,西与海门市毗邻,属典型东部沿海滩涂地形地貌,经济较为发达,人为活动对其植被分布影响较大,现有全国中药资源普查信息系统随机自动生成的样地未能反映启东市的实地生态,结合水生、耐盐中药资源调查暨江苏省第四次中药资源普查试点工作实践,提出基于空间分层随机抽样的平原地区普查方案,能够较为真实、全面的反应平原地区的资源概况,可为全国第四次中药资源普查工作全面实施后,平原地区及土地利用性质变化较大区域的资源普查提供方法学参考。
Qidong City, Jiangsu Province, belongs to the sedimentary plain of the Changjiang Estuary, with the Yangtze River to the south, the Yellow Sea to the east and the north, and adjacent to Haimen City in the west. It belongs to the typical coastal landform of the east coast and enjoys relatively developed economy. Anthropogenic activities have a great influence on the vegetation distribution. According to the survey of aquatic and salt-tolerant Chinese medicine resources and the fourth pilot project of traditional Chinese medicine resources census in Jiangsu Province, a random sample of randomly generated samples from the Census of Chinese Medicine Resources General Information System was not generated. The plain census program can provide a more realistic and comprehensive overview of the resources in the plain and provide a reference for the census of the resources in the plains and areas with large changes in the nature of land use after the full implementation of the fourth census of Chinese traditional medicine resources.
