新疆阿勒泰地区不同水体浮游生物种群特点的初步研究

１９８６—１９８９年调查了新疆阿勒泰地区３０处不同水体的浮游生物。浮游植物以硅藻为主，占５９．２％，浮游植物季节变化呈单峰型。湖泊、水库、坑塘和河流的浮游植物生物量分别为４．３５９ｍｇ／Ｌ、２．７０６ｍｇ／Ｌ、６．２３１ｍｇ／Ｌ和１．９７６ｍｇ／Ｌ，浮游动物生物量分别为３．３２ｍｇ／Ｌ、３．７７３ｍｇ／Ｌ、１．８５９ｍｇ／Ｌ和０．５４４ｍｇ／Ｌ。全区湖泊、水库、坑塘浮游生物产量为９９０９６．７１Ｔ，鱼产潜力４３９８２．４Ｔ。讨论了水体营养类型的划分和渔业利用问题。

STUDY ON POPULATION CHARCTERISTICS OF PLANKTON IN VARIOUS WATERS OF XINJIANG ALETAI AREA

Plankton of 30 various' waters was investigated in Xinjianj AIetai area. Bacillariophyta was dominant population of phytoplankton (59.2% ),and the seasonl change of phytoplankton was single peak form, and biomass of phytOPlankton of lakes, reservoirs, pools and rivers were 4. 359 mg/L, 2.706 mg/L, 6.231 mg/L and 1.976 mg/L, and biomass of Zooplankton were 3.320 mg/L, 3.773 mg/L, 1. 859 mg/L and 0.544 mg/L,and productivity of phytoplankton was 99096.71 T in lakes, reservoirs and pOOls of this area, the potential fish productivity was 43982.4 T, and trophic claSsification of the waters and fishery utilizing were disscussed.
