四川省甘孜、阿坝、凉山三个民族自治州,位于四川盆地西北部,东经98°至140°,北纬26°至34°之间,海拔均在1000米以上,属青藏高原的一部分。境内横断山脉横贯其中,邛崃山、大雪山、大凉山分布其间,西南由金沙江环抱,与西藏、云南一水相隔,雅砻江、大渡河、岷江等长江三大支流纵贯三州而南流入长江。常年平均气温在19℃以下,平均气压在880毫巴以下(1气压=760毫米汞柱=1013毫巴),空气中氧含量在19%以内,均较盆地为低。由于高原抬升,出现了巨大高差,不同海拔高度也就存在着不同的生境。仓库害虫由于受到这些不同生境的影响,必然导致种群分布的特异性。现就四川高原仓库害虫种群分布
The three ethnic autonomous prefectures of Ganzi, Aba and Liangshan in Sichuan Province are located in the northwestern part of the Sichuan Basin. They are between 98 ° and 140 ° East longitude and between 26 ° and 34 ° North latitude at altitudes of more than 1,000 meters, and are part of the Qinghai-Tibet Plateau. The territory of the Hengduan Mountains runs through them. The Qionglai Mountains, the Snowy Mountains and the Daliangshan are distributed along the southwest by the Jinsha River. Separated from Tibet and Yunnan, the three tributaries of the Yalong River, Dadu River and Minjiang River run through three states and south Flow into the Yangtze River. The annual average temperature is below 19 ° C and the average pressure is below 880 mbar (1 bar = 760 mm Hg = 1013 mbar), and the oxygen content in the air is below 19%, both lower than in the basin. Due to the elevation of the plateau, a huge elevation difference has appeared, and different habitats exist at different altitudes. Due to the impact of these different habitats, warehouse pests inevitably lead to the specific distribution of the population. Now on the Sichuan plateau warehouse pest population distribution
