摘　　要：为弄清陕西蝗虫的生物多样性及生态地理分布,采用G-F指数法,对近年陕西蝗虫的生物多样性及其分布进行了研究。结果表明:陕西目前已知蝗虫有3总科9科57属111种,秦巴山区的蝗虫分布占总种数的72.97%,渭河平原占40.54%,陕北高原占47.74%。秦巴山区单科种较多,而陕北蝗虫单科种较少,陕北高原和秦巴山区多样性指数与蝗虫的种类分布相反。The biodiversity and eco-geographical distribution of locusts in Shaanxi Province in recent years were studied by G-F index method.The results showed that there were 111 locust species belonging to 57 genera,nine families and three total families in Shaanxi Province.72.97% of locusts distributed in Qinba mountainous region,40.54% in Weihe Plain,47.74% in North Shaanxi Plateau.The single species in single families were abundant in Qinba mountainous region,but rare in North Shaanxi Plateau.The biodiversity index and locust species distribution in North Shaanxi Plateau were opposite to that in Qinba mountainous region.
