采用系统抽样技术和样带法,对浙江12个重点蛇种的数量和生态分布进行了研究.初步查清了这12个蛇种在其分布区范围的种群出现密度和种群资源量,分别为:赤链蛇,2.97条/km2,60.47×104条;王锦蛇,4.57条/km2,93.05×104条;玉斑锦蛇,0.39条/km2,7.94×104条;黑眉锦蛇,0.83条/km2,33.80×104条;赤峰锦蛇,5.09条/km2,0.36×104条;灰鼠蛇,1.04条/km2,21.17×104条;滑鼠蛇,0.74条/km2,15.07×104条;乌梢蛇,4.08条/km2,83.07×104条;银环蛇,1.35条/km2,41.23×104条;眼镜蛇,2.80条/km2,57.01×104条;五步蛇,1.40条/km2,27.96×104条;蝮蛇,4.37条/km2,63.10×104条.生态分布的统计研究表明:在小地形类型上,下坡和山谷地带蛇类数量最多,主要为王锦蛇、灰鼠蛇、滑鼠蛇、乌梢蛇、眼镜蛇和五步蛇;平地上次之,主要是赤链蛇、蝮蛇和银环蛇;黑眉锦蛇和玉斑锦蛇在平地与下坡及山谷地带分布数量不相上下.在小生境类型上,以灌草丛上蛇类最多,主要是眼镜蛇、滑鼠蛇、五步蛇和黑眉锦蛇;农田和旱地次之,主要为赤链蛇、灰鼠蛇和银环蛇;再是园地和乔木林,玉斑锦蛇主要在园地,五步蛇集中分布在灌草丛和乔木林;乌梢蛇和王锦蛇在上述生境均有分布,在灌草丛上稍占优势;蝮蛇则多见于农田、旱地、园地和灌草丛.文末,提出了如何保护好浙江蛇类资源的对策和建议.
