摘要
长江三角洲地处以上海为中心的经济发展区，是我国经济实力最强、产业规模最大的三角洲，具有良好的自然、社会、人文和区位条件，农业发展水平居全国前列。但是经济发展和高密度人口也给农业进一步发展带来沉重的压力，人地矛盾和人粮矛盾加剧严重危害了长江三角洲农业的可持续发展，同时全区农业发展水平受到自然、经济和历史因素的影响，存在较大的地域差异。从长江三角洲农业发展的地域差异出发，选取与农业发展密切相关的经济、人口和资源等地理要素，对长江三角洲４个市农业发展地域差异进行聚类分析，并根据分析结果提出不同农业发展区域实行农业可持续发展的目标和途径。
With Shanghai being its developing core, Yangtze River Delta is the largest, richest andmost developed area in China. its agriculture is also among the most advanced of our country dueto its excellent natural social and economic conditions. But at the same time economy developmentand high-density population has brought pressure to the further development of agriculture. Thecontradictions between population and limited land and between population and food hinder itssustaina13le development. Based on the regional differentiation of agriculture level of the area, using geographic factors of economy, population and resources, we did cluster analysis on the 14cities and thus proposed related sustainable strategies.
