Polder is a unique form of reclaimed farmland steeped in human history of long-term adaptation to nature. It embodies traditional agricultural technologies, water conservancy technologies and the culture of the agricultural society, providing great value in terms of agricultural heritage. The polder system in Gaochun, Nanjing was born out of the exploitation and use of the lakeside intertidal zone and is a typical example of Jianghuai polders in the Yangtze River delta region. However, because of neglect of its heritage value, the Gaochun polder system is facing the impact of farmland modernisation, and it is urgent to affirm its value and implement dynamic protection. This research explores the historical development and spatial features of the Gaochun polder system, and evaluates its heritage value within the framework of GIAHS (Globally Important Agricultural Heritage Systems) from aspects of (1) food and livelihood security; (2) agro-biodiversity; (3) local and traditional knowledge systems; 4) cultures, value systems and social organisations; and 5) landscapes features. Based on our recognition of the agricultural heritage value of the Gaochun polder system, we put forward suggestions for its dynamic conservation and adaptive management while maintaining its productive functions.

南京高淳the田制农业遗产价值

der田是人类长期适应大自然的历史中耕地的一种独特形式。它体现了传统的农业技术，水利技术和农业社会的文化，在农业遗产方面具有巨大的价值。南京高淳的田系统源于湖滨潮间带的开发和利用，是长江三角洲地区江淮pol田的典型例子。但是，由于高淳田系统遗忘了其遗产价值，正面临着农田现代化的冲击，因此迫切需要确认其价值并实施动态保护。这项研究探索了高淳der田系统的历史发展和空间特征，并在全球农业重要遗产（GIAHS）框架内从以下方面评估其遗产价值：（1）粮食和生计安全；（2）农业生物多样性；（3）地方和传统知识体系；4）文化，​​价值体系和社会组织；5）景观特征。在认识到高淳system田系统农业遗产价值的基础上，我们提出了在保持其生产功能的同时，对其动态保护和适应性管理提出建议。
