基于RS和GIS技术的河北省鸡形目鸟类分布格局

收集和整理河北省鸡形目鸟类的分布资料，借助GIS的绘图功能，把解译的遥感影像数据数字化为植被类型图和地貌图；根据文献和标本记录的地理位置和野外考察记录，做出河北省鸡形目鸟类的点分布图；根据鸡形目鸟类与其生境之间的相互依赖关系，定义鸡形目鸟类的适宜生境类型，利用GIS技术的分析、提取和叠加功能，提取每种鸡形目鸟类的适宜生境类型图，预测河北省鸡形目鸟类的总体分布格局。结果表明：河北省鸡形目鸟类物种丰富度地区主要集中在坝上高原区和燕山太行山山地区；河北省鸡形目鸟类可分为全省广布种(鹌鹑和雉鸡)、燕山太行山山地和坝上高原分布种(石鸡、斑翅山鹑、勺鸡)和局部地区特征种(黑琴鸡、黑嘴松鸡、花尾榛鸡、褐马鸡)3种类型。

Galliformes Distribution in Hebei Province Based on RS and GIS Techniques

The geographical distribution of Galliformes in Hebei Province was analyzed by use of the correlative references of the distribution.The RS image was digitized to the vegetation map and the geomorphologic map utilizing the drawing function of GIS techniques.The dot distribution of the Galliformes was drawn with GIS techniques from the records of the references and the specimens and field survey.The suitable habitat of the Galliformes was defined through the relationship of birds and the environment.The suitable habitat types of every species was picked up and the distribution of the Galliformes in Hebei Province was forecasted by use of the function of analyzing,picking-up and splicing.The result shows that the Galliformes in Hebei Province mainly distribute in the Taihang-Yanshan Mountains and the Bashang plateau,and that they can be divided into three types,namely,the species distributing in the whole province (Coturnix coturnix and Phasianus colchicus),the species distributing in the Taihang-Yanshan Mountains and the Bashang plateau (Alectoris chukar,Perdix dauuricae and Pucrasia macrolopha),and the species distributing in specific parts (Lyrurus tetrix,Tetrao parvirostris,Bonasa bonasia and Crossoptilon mantchuricum).
