一、水库的自然概况哈尔滨市西泉眼水库距哈尔滨市区112公里,占地面积40.86平方公里,位于阿城市平山镇西泉眼屯。西泉眼水库距城市较远,免受污染,水质较为清新。西泉眼水库为调节型水库,总库容为4亿多立方米,养鱼水面达4.4万余亩。西泉眼水库形成后淹没了大量农田、耕地、林地和沼泽,丰富了水中的营养物质。水库周围土壤植被良好,土壤中所含有的营养元素被雨水冲刷随迳流进入库区,植物腐烂分解释入进入库区水体,使水中的营养物质丰富。生物生态环境多样且复杂,造成西泉眼水库浮游生物种类组成丰富、数量多。在这么宽广的大水面里,主要靠水库中的天然饲料供给鱼类摄食,因而必须定期了解水库中的天然饲料组成和变动情况,制定科学的鱼类放养计划。
First, the reservoir’s natural profile Harbin City, West Springs Reservoir 112 kilometers away from Harbin, covers an area of 40.86 square kilometers, located in the town of Pingshan, A City, West Eye Tuen. West Springs Reservoir reservoir far from the city from pollution, water quality is relatively fresh. Xiquanyan Reservoir is a regulated reservoir with a total storage capacity of more than 400 million cubic meters and a fish water surface of more than 44,000 mu. After the formation of the reservoir, Xiquan Eye drowned a great deal of farmland, cultivated land, woodland and swamps and enriched the nutrients in the water. The soil around the reservoir is well-planted. The nutrients contained in the soil are infiltrated by rainwater into the reservoir area. The decomposed plants are decomposed and released into the water body of the reservoir so that the nutrients in the water are abundant. Biological diversity and complexity of the ecological environment, resulting in planted species of Xiquanyan reservoir rich in abundance, a large number. In such a wide area, the natural feeding of fish mainly depends on the natural feed in the reservoirs. Therefore, it is necessary to regularly understand the composition and changes of natural feed in the reservoirs and formulate scientific fish stocking plans.
