运用3S技术,分析和探讨了河南省内黄县1979—2007年的植被覆盖度变化特征。结果显示,该区30年间的植被覆盖度变化显著。具体为：高覆盖度和中高覆盖度逐年上升,而中覆盖度、低覆盖度和极低覆盖度出现不同程度的降低,中覆盖度降低的幅度较小,而低级覆盖度下降幅度较大。结论表明研究区的生态环境质量呈现不断上升的态势。一方面反映了人口增长和经济建设需求对植被覆被变化的积极影响,另一方面反映相关部门重视生态环境的建设,研究区人口素质提高环保意识增强。

Based on 3S technology,this paper analyzes variation characteristics of vegetation coverage in Neihuang County from 1979 to 2007.The results show that its variation is very obviously within 30 years.In detail,high coverage and middle-high coverage is growing year by year,while the middle coverage,low coverage is reducing to some extent,especially the low coverage reduction rate is declining significantly.The conclusions indicate that regional eco-environmental quality is rising constantly.In one hand,this tendency reflects the positive impact of the need of population growth and economic construction.In another hand,it reflects that the consciousness of environmental protection is enhanced,because the population quality of research area was improved,and relevant departments pay attention to ecological environment greening.
