吉林省鼠疫自然疫源地景观特征的研究

A Study on the Landscape Characteristics of Plague Infectious Areas in JiLin Province

目的研究各种景观要素对鼠疫自然疫源性疾病的综合影响,并对这些影响进行评价。方法利用地理信息系统(G IS)、全球卫星定位系统(GPS)和遥感(RS)技术,结合1∶5万地形图、数字化仪等方法对疫源地景观进行研究。结果农田开垦、植树造林、水利建设等人类经济活动的影响,吉林省鼠疫自然疫源地空间结构较发生了明显变化。结论地貌、土壤及植被等地理要素直接影响鼠疫主要宿主动物的数量及分布。

Objective To study the comprehensive influence of all kinds of landscape major factors on plague natural infectious diseases and evaluate it. Methods Combine GIS, GPS and RS techniques with I .50 000 topographic maps, numerical apparatus etc to research the landscape of infectious areas. Results Because of the humans economic actions such as cultivating farmlands, planting trees and afforestation, building water conservancy etc, obvious changes have happened in the space structures of plague natural infectious areas of JiLin province. Conclusions Geographical major factors such as landform, soil and vegetation etc effect on the amount and the distribution of plague main host animals.
