摘要

[目的] 探究山东半岛与黄河几字弯两大区域的土地生态安全水平差异

为实现黄河流域生态保护与高质量发展

推动"共同抓好大保护

协同推进大治理"战略提供现实依据。[方法] 运用熵值法、核密度估计、马尔科夫链与障碍因子模型等方法

对黄河流域两大区域的土地生态安全进行动态评价。[结果] (1)在水平变化上

两大区域的土地生态安全增速均呈"倒U"形态势

山东半岛的土地生态安全水平明显高于黄河几字弯

但黄河几字弯的增长速度更快。(2)在时间上

两大区域土地生态安全均呈现"单核"演变特征

山东半岛区域差异有扩大态势

几字弯区域差异则有缩小态势。在空间上

两大区域均呈现出"东中部高—西部低"的空间分布态势。(3)动态演化特征上

两大区域土地生态安全等级演变具有"路径依赖"与"自身锁定"效应。(4)山东半岛土地生态安全受人均耕地面积、地均化肥农药施用量等影响;黄河几字弯土地生态安全受景观破碎度、森林覆盖率等影响。[结论] 未来山东半岛与黄河几字弯既要根据区域优势分类施策

也要从流域全局出发

协同提升黄河流域土地生态安全水平。

Abstract

[Objective] This study intends to comprehensively explore the land ecological security situation of the Shandong Peninsula and Jiziwan of the Yellow River

provide a realistic basis for realizing the ecological protection and high-quality development of the Yellow River Basin and promoting the strategy of "jointly grasping the great protection and jointly promoting the great governance". [Methods] The entropy method

kernel density estimation

Markov chain and obstacle factor model

and other methods were applied. [Results] (1) In terms of level change

the growth rate of land ecological security in the two regions was "inverted U" type. The level of land ecological security in Shandong Peninsula was obviously higher than that Jiziwan of the Yellow River

but the growth rate of Jiziwan of the Yellow River was faster. (2) In terms of time

the land ecological security of the two regions had the characteristics of "single core" evolution. The regional differences in Shandong Peninsula were expanding

while the regional differences in Jiziwan were narrowing. In space

the two regions showed a spatial distribution trend of "high in the middle east and low in the west". (3) On the evolution characteristics

the evolution of land ecological security level in the two regions had the effects of "path dependence" and "self-locking". (4) The ecological security of land in Shandong Peninsula was affected by the per capita cultivated land area and the average application amount of chemical fertilizers and pesticides. The ecological security of land in Jiziwan of the Yellow River was affected by landscape fragmentation and forest coverage. [Conclusion] In the future

Shandong Peninsula and Jiziwan of the Yellow River should not only classify and implement policies according to regional advantages

but also proceed from the overall situation of the basin to jointly improve the land ecological security level of the Yellow River Basin.
