环渤海区域林蛙资源及其保护

目的对环渤海区域进行物种多样性的调查研究,通过本研究为这一区域的林蛙保护提供科学依据。方法根据多年来的野外调查,结合已有研究进行分析评估。结果本区域分布林蛙有6种,其中黑龙江林蛙、徂徕林蛙和昆嵛林蛙分布区域狭窄,徂徕林蛙和昆嵛林蛙不仅是中国的特有种,也仅分布于本区域的山东省。林蛙作为重要的自然资源,药用价值巨大,养殖产业不断发展。随着养殖业的发展,林蛙保护问题日显突出。结论环渤海区域是中国林蛙属物种多样性最为丰富的地区,也是东北林蛙养殖的主要地区,应加强保护和合理开发利用。

Resources and Conservation of Brown Frogs at the Area around Bohai Sea

Objective The brown frog diversity is richest at thearea around Bohai sea in China. This area is a ma- jor site of Rana dybowskii farming. The aim of this research is to supply scientific information for the conservation of the brown frogs. Methods The field investigations were analyzed and assessed with relevant research arti- cles. Results 6 species were found,and R. amurensis,R. Culaiensis and R. Kunyuensis live in smaller area in the area. R. Culaiensis and R. Kunyuensis are Chinese endemic and only distributed in Shandong province. As important natural resources,the brown frogs have tremendous medical value with a much developing farming. As a result of farming,their conservation problems became more and more serious. Conclusion Based on the analysis of re- source use and conservation status, the suggestions of conservation and management were supplied by us.
