摘要

通过对研究区CBERS—2影像进行预处理、建立解译标志、人工判读、分类等过程得到了陕西省县级土地利用数据库;以此为依据

按照生态环境质量评价技术标准进行生态环境质量指数计算

最后得到该区2004年生态环境质量综合评价结果:陕北黄土高原地区生态环境质量一般

榆林地区环境较差;中南部地区环境质量良好

其中秦岭地区环境质量优。将计算结果与该区2000年的评价结果对比分析得出:全省环境质量总体上呈现不同程度的提高

其中关中平原地区生态环境显著改善

但也有少数地区环境继续恶化。

Abstract

The county-level landuse data base of Shaanxi Province is established by pre-treat ing CBERS—2 images

setting up interpretation indexes and classifying landuse and so on. Accordingly

the environmental quality indexis calculated in terms of the evaluating standards of environmental quality

and the integrated evaluation of ecological environmental quality for Shaanxi Province in 2004 is eventually completed. The evaluat ing result shows that the quality in the north area is on average; in the Yulin area

poor; in the central and south area

good; and in the Qinling area

excellent. Comparing the result with the integrated evaluating result in 2000 indicates that the overall environmental quality of Shaanxi is improved

and the environment of the cent ral area is boosted distinctly while few individual areas continue to deteriorate.
