摘要

[目的] 通过对耕地保护现状空间格局成因及其空间相关性分析，划分科学的耕地整治规划分区，为进一步优化崆峒区耕地布局，提升耕地质量，科学利用、保护耕地提供参考。[方法] 以甘肃省平凉市崆峒区为例，采用景观格局指数法、多目标决策法、Spreaman秩相关法、聚类分析法，选取耕地坡度、耕地保护政策、城镇化影响来分析耕地景观格局现状与其在空间上的存在的协同或权衡关系，构建耕地保护格局相关性分析评价指标体系。[结果] ①研究区整体上耕地景观格局指数2010—2022年上升3.55%，耕地集聚程度大部分区域呈现下降趋势，但在整个过程中呈现波动。区域土地利用程度整体上呈上升趋势，各乡镇耕地布局特征及土地利用程度差异明显。②耕地保护指数2022年较2010年上升315.30%，2°～6°耕地增加120.96%，15°～25°耕地减少32.64%，>25°耕地减少100%，耕地质量提升明显，与耕地景观格局在空间上高度协同；城镇化影响指数呈上升趋势。2010—2022年城镇化影响指数上升25.17%，城镇化对耕地布局影响加大，与耕地景观格局在空间上存在权衡关系。③划分耕地质量提升重点区、耕地质量提升一般区、耕地新增开发潜力区、耕地协调保护区等4个耕地整治规划单元。[结论] 甘肃省平凉市崆峒区耕地布局特征各乡镇差异性明显，耕地整体保护成效明显。影响研究区耕地空间格局的主要因素为政策因素、城镇开发影响以及农民种植意愿和耕地保护意识等。

Abstract

[Objective] Through analying the causes of the current spatial pattern of cultivated land protection and its spatial correlation

the scientific zoning of cultivated land renovation planning was divided to provide reference for further optimizing the layout of cultivated land

improving the quality of cultivated land

and scientific utilization and protection of cultivated land. [Methods] Taking Kongtong District

Pingliang City

Gansu Province as an example

landscape pattern index method

multi-objective decision-making method

Spreaman rank correlation method and cluster analysis method were used to analyze the synergistic or tradeoff relationship between the current situation of cultivated land landscape pattern and its spatial existence by selecting cultivated land slope

cultivated land protection policy and urbanization impact

and to construct the correlation analysis and evaluation index system of cultivated land protection pattern. [Results] ① As a whole

the cultivated land landscape pattern index of the study area increased by 3.55% from 2010 to 2022

and the degree of cultivated land agglomeration showed a downward trend in most regions

but it fluctuated during the whole process. The regional land use degree showed an upward trend on the whole

and the characteristics of cultivated land layout and land use degree of each township were significantly different. ② The cultivated land protection index in 2022 increased by 315.30% compared with 2010

the cultivated land on 2°-6° slope increased by 120.96%

the cultivated land on 15°-25° slope decreased by 32.64%

and the cultivated land in > 25° decreased by 100%

which was highly coordinated with the cultivated land landscape pattern in space. The urbanization impact index showed an upward trend

which increased by 25.17% from 2010 to 2022. The urbanization impact on cultivated land distribution increased

and there was a significant spatial balance between urbanization and cultivated land landscape pattern. ③ Four units of cultivated land renovation planning were divided as cultivated land quality improvement key area

cultivated land quality improvement general area

cultivated land new development potential area

cultivated land coordination protection area. [Conclusion] The distribution characteristics of cultivated land in Kongtong District of Pingliang City

Gansu Province are different among different towns

and the overall protection effect of cultivated land is obvious. The main factors affecting the spatial pattern of cultivated land in the study area are policy factors

the impact of urban development

farmers' planting willingness and cultivated land protection awareness

etc.
