伊犁河南岸昆虫区系及灌区建设对其影响的预测

Insect Faunas and the Impacts from the Construction of the Irrigated Area on the Southern Side of the Yili River in Xinjiang

从新疆巩留县往西的察布查尔县境内,约2 000 km2的伊犁河南岸荒漠是未来灌区项目建设的所在地。2002年8月,对该地及其南缘和北缘地带的昆虫区系进行了调查,查明计有291种昆虫,隶属于15目87科239属,并对未来灌区建设对昆虫区系的影响进行了预测。

The construction of the irrigated area will be implemented in near future in the desert with an area about 2 000 km2 in Qapqal Xibo Autonomous County on the southern side of the Yili River, where the natural environment is severe and the ecosystems are extremely vulnerable. The construction in this region will undoubtedly promote the regional social and economic development, however, the natural environment and the structure of the biological communities including the insect faunas will be changed. Therefore, the insect faunas in this region were investigated in August 2002, and it is revealed that there are 291 species of insects in 239 genera, 87 families and 15 orders in the investigated area. Moreover, the impacts of the construction on the insect faunas are predicted. It is considered that the implementation of the project will change the plain desert into the farmland oasis, greatly improve the natural environment and the ecosystems, and increase the economic returns, however, the impacts of the construction on the insect faunas should be paid a great attention to.
