[目的]中哈边境蝗虫跨境迁飞危害常造成严重损失,掌握蝗虫迁出区和迁入区生态条件异同是提高监测预警水平的基础.[方法]采用野外调查与室内分析相结合,比较哈萨克斯坦境内阿拉湖蝗区和中国新疆塔城边境蝗区生态特征的异同.[结果]塔城边境蝗区与阿拉湖蝗区地势平坦,平均海拔444.60±5.58 m,无差异显著(P＞0.05),两蝗区主要植被和蝗虫种类相似；塔城边境蝗区与阿拉湖蝗区土壤pH 值分别为8.80±0.17、8.16±0.14,含盐量分别为5.95±1.79、0.71±0.10 mg/g,有机质含量分别为46.94±4.37、22.53±2.74 g/kg,均差异显著(P＜0.05)；除Ca2+和CO32-,Cl-、SO42-、K+、Na+、Mg2+、HCO3-含量均差异显著(P＜0.05)；两蝗区20 a(1980～1999年)年均气温和降水量无差异显著(P＞0.05),年、季节平均气温和降水量5 a 滑动趋势差异显著(P＜0.05).[结论]中哈边境相邻蝗区的植被种类、土壤理化性质及气候变化特征有利于蝗卵安全越冬、孵化和生长发育,是蝗虫适宜的生境及产卵场所,相邻蝗区生态条件的相似性和差异性表明蝗虫跨境危害仍将是中哈边境蝗区重要生物灾害之一.
