摘要
凭借着独一无二的地质、地貌、海洋、气候、土壤和生态特征 ,江苏潮滩拥有丰富的自然资源 ,然而却又受着不利自然条件及不合理人类活动的限制。江苏潮滩沉积表现出 4个水平相带 :草滩 (湿地 )沉积带、盐蒿泥滩沉积带、泥—砂混和滩沉积带、粉砂滩沉积带。潮滩是极为脆弱的生态系统 ,它极容易受到湿地围垦、低效的生产方式、酷取滥采、环境污染等人类扰动的破坏。基于以上认识 ,提出顺应潮滩自然演变 ,人类活动与潮滩沉积环境的和谐开发利用及保护模式。
With unique features in geology, geomorphology, oceanography, climate, pedology and ecology, the Jiangsu coast is rich in natural resources, but, is constrained by various unfavorable natural conditions and faces human-activity-induced problems. The Jiangsu coast are divided into 4 distinctive zones from HWSL to LWSL: (Ⅰ) grass flat (or salt marsh); (Ⅱ) Suaeda Salsa mud flat: (Ⅲ)mud-silt flat; (Ⅳ) silt (or fine sand) flat. The tidal flat is sensitive ecosystems and can be damaged and/or destroyed by human activities such as wetlands reclamation, low-efficiency production, environmental pollution and irrational guidance. Therefore, the environment and resources exploitation must be based on sustainable development strategy. According to the characteristics of the natural ecosystem, we proposed a harmonized development model of the tidal flat wetlands of Jiangsu coast.
