| 摘要: |
| 以河北曲周县342个农村居民点为评价单元,从压力源-压力流-压力汇的角度构建农村居民点适宜性评价,采用频度统计法、理论分析法、专家咨询法设置和筛选评价指标,确定各指标因子的权重;计算农村居民点的压力源、压力流和压力汇各指标值及农村居民点适宜性评价值,最后依据评价结果将研究区划分了5种空间格局优化模式。结果表明:全县农村居民点压力适宜性弱的占全部村庄的45.61%,适宜性一般的村庄占32.74%,适宜性较强的村庄很少,占21.65%。本研究尝试将压力论应用于农村居民点整理,研究结果可为农村土地整治提供有益探索和理论支持。 |

| Abstract: |
| With 342 rural residential sites in Quzhou County as evaluation units,the suitability evaluation was made from three aspects of pressure source,pressure flow and pressure sink.The evaluation index were set up and screened with the methods of frequency analysis,theoretical analysis,expert consultation.Following determination of the weighted index factor,the values of pressure source,flow and sink were calculated and then estimated the rural residential suitability.Finally,the research district was divided into 5 kinds of space pattern optimization model.The evaluation results showed that 45.61% of the rural residential sites were at low suitability 32.74% at mediate suitability and 21.65% at high suitability.The study was an attempts to apply the pressure theory in rural residential land consolidation,the results might provide an useful exploration and scientific support for rural land consolidation. |
