- 摘要:
- 黑龙江省大庆市土壤存在着严重盐渍化现象,土壤盐渍化已成为影响当地农业生产和土壤资源可持续利用的阻碍因素。基于2001年1∶10 000土地利用现状图和2009年TM影像,利用“3S”技术进行盐渍化信息提取,得出盐渍化面积及其变化率。在分析该地区的盐渍化程度和驱动因子的基础上提出了治理对策。结果表明:盐渍化面积2001年为76 915 hm2,2009年为79 254 hm2,变化率为0.33%。盐渍化问题严重,应通过生态工程措施、施枯草、水利工程等措施治理盐渍化问题。
- Abstract:
- Soil salinization is serious in Daqing city of Heilongjiang province.Soil salinization has been effected obstructive factor on local agricultural production and sustainable utilization of land resources.The information of salinization was extracted by applying the technology of ‘3S’ technology,based on 1∶10 000 land-use map of 2010 and TM image of 2009,then,area and change percentage of salinization were obtained.At the same time,countermeasures were proposed on the basis of analysing the degree of salinization and driving factor.The results showed that:salinization area was 76 915 hm2 in 2001 and 79 254 hm2 in 2009,and the change percentage was 0.33%.It indicated that salinization in Daqing was very serious.It should control the salinification by ecological engineering measures,dry grass and water conservancy project.
