江苏省沿海野生栝楼资源分布特点与评价

Distribution Characteristics and Evaluation of Wild Trichosanthes kirilowii Maxim. in Coastal Areas of Jiangsu Province

对江苏省沿海野生栝楼的形态、分布、生态环境与群落类型等进行了资料分析、踏查、样地调查。结果表明,栝楼在东台、射阳沿海滩涂较多分布于人工刺槐林、银杏林下和林缘,在村落周围和滩涂草甸也有分布,极少分布于农田和沟渠。对东台市沿海130.04 km2代表区域内天花粉蕴藏量估算值达731.663 7 t;射阳县沿海113.89 km2代表区域内天花粉的蕴藏量约为125.618 6 t。对江苏省沿海栝楼野生资源的生产发展提出了建议,为开展栝楼野生资源的可持续利用奠定基础。

The morphology, distribution, eco-environment and coenotype of coastal wild Trichosanthes kirilowii Maxim. in Dongtai City and Sheyang County were investigated by data collection, reconnoiter and sample-plot surveys in coastal areas of Jiangsu Province. Results showed that wild T. kirilowii was mainly living in the artificial Robinia pseudoacacia, Ginkgo biloba forests and forest edges. It distributed around villages, beach meadows, and rarely in farmland and ditches. It was esmated that there were 731. 663 7 tons of wild Trichosanthis Radix in the 130. 04 km^2 representative region of Dongtai, and 125. 618 6 tons of wild Trichosanthis Radix in the 113. 89 km^2 representative region of Sheyang. A proposal is made with regard to the production development of wild resources of coastal T. kirilowii, in Jiangsu, laying a foundation for a sustainable exploitation.
