东北地区黑土保护与区域发展综合评价及耦合协调研究

Comprehensive evaluation and coupling coordination of black soil protection and regional development in Northeast China

本文通过熵值法构建指标体系对东北黑土区内县级单元2020年的区域综合发展水平(经济与社会)和黑土保护情况(数量与质量)进行了评价,运用耦合协调度模型测度了黑土保护与区域发展的耦合协调关系及类型,并分类型对东北地区黑土保护利用与区域高质量发展提出了针对性建议。研究表明:①黑土区内大量区域发展水平较低的县级单元在东北地区中部形成了明显的经济社会发展塌陷区,表明黑土资源的利用并没有成为东北中部地区发展的主要推动力。②东北地区的黑土保护与区域发展之间的耦合度水平较高,表明黑土保护与区域发展之间相互作用的程度较强,有必要重视二者关系的协调;2/3的县级单元处于黑土保护与区域发展耦合协调过程中的失调阶段,表明分类型协调黑土保护与区域发展关系的任务非常紧迫。③基于黑土保护与区域发展的综合水平及二者的耦合协调关系,本文认为东北黑土区可划分为:区域发展弱−黑土保护弱、区域发展弱−黑土保护好、区域发展弱−黑土保护强、区域发展好−黑土保护弱、区域发展好−黑土保护好、区域发展好−黑土保护强、区域发展强−黑土保护好7种类型区,有必要依据类型区特征分类分区协同推动黑土保护与区域发展工作。

Ensuring national food security is an important part of implementing the national strategy of northeast revitalization,and the coordination between black soil protection and regional development is an important practical problem to be solved in the development of Northeast China.This article comprehensively evaluates the regional development and black soil protection of the county units in 2020 by constructing the index system,using the coupled coordination degree model to measure the coupling and coordination between black soil protection and regional development,and put forward the targeted measures of black soil protection and regional high-quality development of different types.The study found that:1)A large number of county-level units with low level of regional development in black soil area have formed obvious regional development subsidence areas in the central part of northeast China,indicating that the utilization of black soil has not become the main driving force for the development of central Northeast China.2)The coupling degree between black soil protection and regional development in Northeast China is strong,which indicates a high degree of interaction between regional development and black soil protection,and the relationship between the two needs to be valued;2/3 county units'black soil protection and regional development are in the dysregulation stage in the coupling and coordination process,indicating that coordinating the relationship between black soil protection and regional development by different types is very urgent.3)Based on the comprehensive level of black soil protection and regional development and the coupling coordination,the northeast black soil area can be divided into seven types:Weak regional development-weak black soil protection;Weak regional developmentgood black soil protection;Weak regional development-strong black soil protection;good regional development-weak black soil protection;Good regional development-good black soil protection;Good regional development-strong black soil protection;Strong regional development-good black soil protection,according to each type's area characteristics,can promote black soil protection and regional development by classification.
