摘要

基于2004 年SPOT 多光谱影像、2004 年耕地地力调查数据等， 以山东省即墨市为例， 开展耕地质量评价 研究。采用RS 技术， 从SPOT 多光谱影像中提取耕地质量评价因子， 如反映土壤肥力状况、水分状况、土壤退化状 况等不同信息的NDVI、DVI、RVI， 结合坡度信息、土地利用程度等， 构建了基于RS 技术的耕地质量评价指标体系。 根据压力- 状态- 响应框架( PSR) ， 构建评价模型， 旨在开展遥感技术在耕地质量评价中的应用研究。评价结果表明， 即墨市耕地质量普遍较好。研究将该市耕地分为六个等级， 并针对不同等级因地制宜地提出了耕地资源保护的政 策建议。

Abstract

The cultivated land quality assessment study was carried out in Jimo city, Shandong Province, based on SPOT multispectral remote sensing image (2004) and data using in cultivated land fertility survey in 2004. Cultivated land quality assessment indicators were abstracted from SPOT multispectral image, e.g. NDVI, DVI and RVI, which represented soil fertility, water availability and soil degradation respectively. The assessment indicator system was constructed using the indicators mentioned above. By virtue of PSR framework, the assessment model was developed in order to explore the feasibility of RS technology in cultivated land quality assessment. The result showed that local cultivated land prevalently had a good quality. This paper classified the local cultivated land into six grades and corresponding suggestions were put forward respectively to promote policy making for land protection. The paper showed that the model was competent for its work in the study area and evaluation results would supply beneficial information for sustainable land management.

Key words： cultivated land quality assessment; evaluation indicator; Jimo city; RS; SPOT
