Firstly, this paper analyzes their connotation and relationship, which could be simplydescribed thatinvirtueofelementintegratingandstructureoptimizing,agriculturalsystemmayachievemultifunctionalitytomeet increasingly diverse demands. As a case study of Suzhou, it concludes that Suzhou has a LP-dependence onag-ricultural element, and the growth extent of agricultural productivity correlates to the ratio of agricultural laborreduc-ingratetofarmlandreducingrate.AgriculturalstructureofSuzhouchangedwithtime,andintheearly1980sand2000s it was most notable. Correspondingly, agricultural function has experienced a succession process:‘production’,‘production-living’, and ‘production-living-ecology’. At last, based on questionnaires and interviews, some newchar-acteristicsandproblemsofagriculturaldevelopmentincoastaldevelopedregionofChinahavebeenputforward. Meanwhile, some typical patterns of modern agriculture in Suzhou which adapt to system evolving are also broughtup such as export-oriented agriculture, enterprises-leading agriculture, agricultural science and technology parks, charac-teristic and stereoscopic agriculture, tourism and sightseeingagriculture.Keywords: modern agriculture; agricultural system; Suzhou; coastalChina1IntroductionAgriculture is one of the most important economicac-tivities and can be found in most parts of theworld.
