摘要:
在建立"深圳—巴彦浩特"地理样带数据库的基础上,运用Pearson相关方法分析了样带温度和降水的变化对灾情的影响,并探讨了人文因素对旱灾灾情的影响。为了分析不同的自然与人文因素空间组合特征对灾情的影响,通过选取具有代表性的自然与人文因素指标,运用层次聚类方法对样带137个县进行了分析。结果表明:样带的气象灾害以水旱灾害为主,在样带上呈现出明显的区域差异,表现为北方以旱灾为主,南方以水灾为主;降水变异和温度变异是影响气象灾害灾次与持续时间的关键性指标,它们之间具有明显的相关性;人类活动对旱灾的影响明显,其灾次和持续时间与农业产值的比重(一产GDP/总GDP)呈显著的正相关;进一步研究表明,随着一产GDP及有效灌溉面积的增加,能有效缓解旱灾的灾情;聚类分析表明在南北样带上存在六大自然和人文条件组合区。
Abstract:
Based on the database of Shenzhen-Bayanhaote geographic transect, the impact of variability of rain and temperature on meteorologic disasters as well as the impact of human factors on drought are analyzed with Pearson correlation for the transect.To analyze the impact of different combination of natural and human factors on disaster losses, the paper analyzes 137 counties in the transect with hierarchical cluster analysis.The results show that (1) the regional diversity of disasters is evident.Meteorologic disasters mainly consist of flood in the southern regions and drought in the northern regions.(2) The frequency and duration of the meteorologic disasters are affected mainly by the variation of temperature and precipitation.And between them there exist obviously positive correlations.(3) Human activities have a great impact on drought, whose frequency numbers and durations are positively correlated with the ratio of first industrial GDP to total GDP.(4) With the increase of first industrial GDP and available irrigated area, drought losses can be reduced.(5) There are six regions in the transect which are different from each other in terms of natural and human conditions.
