Measurement of multi-dimensional pressure on holistic cultivated land conservation at county level in China under new situations
摘要
Abstract
This study aims to investigate the composition of cultivated land protection pressure in China under new circumstances,measure county level pressure across four dimensions-quantity,quality,ecology,and management,identify areas for optimization,and support decision-making.An indicator system was constructed and spatial statistical methods were employed.The results indicate that nationwide cultivated land quantity protection pressure is generally high,with counties bearing strong-pressure accounting for 14.6％and relatively strong-pressure for 54.7％of the total.Spatially,the pressure index shows characteristics such as being generally higher in eastern and central regions compared to western and northeastern regions,slightly higher in non-major grain-producing areas than major grain-producing areas,lower in districts compared to counties and county-level cities,and somewhat higher in urban agglomeration areas than non-urban agglomeration areas.Cultivated land quality protection and management pressures exhibit a certain degree of spatial clustering with higher overlap,with counties bearing relatively strong or higher pressure accounting for 31.4％and 22.7％of the national total,respectively.Ecological protection pressures show significant spatial differences and distinct regional features,with counties bearing strong-pressure accounting 1.2％and relatively strong-pressure 13.7％of the national total,respectively.Optimization zones for cultivated land quantity,quality,ecology,and management were identified.Recommendations include refining cultivated land certification criteria and implementing differentiated support policies,to scientifically alleviate local protection pressure and enhance multi-dimensional cultivated land protection.关键词
