摘要
如东县沿海高程负2m以上滩涂面积约有6.93×104hm2,每年以25～30m的速度向外淤长,每年可增加滩涂面积330hm2,土地利用潜力较大。但滩涂资源的围垦开发利用也造成了沿海生物多样性减少和滩涂生态系统自我调节功能的降低。如东滩涂资源可持续开发利用应遵循重点保护原则、高效经济原则和资源稳定原则,制定合理的开发规划,逐步形成滩涂养殖业、种植业、盐业、牧业、旅游等产业的多元产业结构。
There are about 69 300 hm2 of the tidal flat above minus 2 m of elevation and approximately 130 000 hm2 of alluvion in Rodong County in Jiangsu,China. Annual expansion of the area of tidal flat is 330 hm2 at the rate of 25～30 m spreading towards the sea,so that there is enormous potentiality for land use. However,the inning and land use of the tidal flat have caused a decrease in biodiversity along the coast and the reduction of self-adjusting function of the ecosystem in the tidal flat. Sustainable utilization of tidal flat in Rudong should keep to the principles of protection,economy,and resources-stabilization. A rational developing plan on tidal flat should be drawn up and a multi-production structure including breed aquatics,planting,salt industry,stock raising and tour gradually shaped.
