楚雄冬春季城郊鸟类多样性初步调查

Primary survey on bird diversity at urbanized area and suburb in Chuxiong city during spring and winter

为了确定楚雄市冬春季城郊区鸟类多样性,采用样点法在4个样地内对随机设置的17个样点进行了调查。本次调查共记录了鸟类2808只次,隶属于4目、16科、44种,雀形目鸟类占调查总数的88.64%,非雀形目占11.36%。结果表明,郊区的鸟类种数(33,27 vs 18,16)、物种多样性(Shannon's index 2.21,2.43 vs 2.12,2.00)、均匀度(0,68,0,75 vs 0.74,0.69)、科属多样性(G-index 3.06,2.92 vs 2.63,2.39 and F-index 6.12,3.64 vs 1.48,0.95)均比城区高,但相对多度(abundance)较低。

To elucidate the variation on bird diversity between urban area and suburb in Chux- iong during spring and winter, point count method was used in 17 sample points within 4 sample plots. 2808 individuals were recorded which belong to 4 ords, 16 families, and 44 species, and pas- seriformes counted for 88.64%, others counted for 11.36%. The result indicated that the suburban had more complex bird community structure in terms of higher species richness （33, 27 vs 18, 16） , higher species diversity （Shannon＇ s index 2.21, 2.43 vs 2.12, 2.00）, higher evenness （0,68, 0,75 vs 0.74, 0.69 ） , higher family and genus diversity （ G - index 3.06, 2.92 vs 2.63,2.39 and F - index 6.12, 3.64 vs 1.48, 0.95） as compared to urban habitat, but the abundance had be converse.
