陕西师范大学邱孟龙小组在研究农田集约化与农业生态系统服务的耦合协调中取得新进展,并提供了来自陕西省黄土高原的证据,这一成果发表在2024年3月18日出版的国际学术期刊《中国地理科学》上。
基于此,本研究以陕西省黄土高原为例,构建综合评价模型,对该地区耕地集约化和农业生态系统服务功能进行量化。以平衡分析和耦合协调度模型评价农田集约化与农业生态系统服务的交互关系,以统计分析和空间自相关分析耦合协调的空间特征和潜在机制。结果表明:2000-2020年,研究区耕地集约化程度和农业生态系统服务功能均处于较低水平,但呈逐渐上升趋势;农业生态系统服务滞后被确定为主要的非均衡发展类型。提高农业生态系统服务供给能力是实现黄土高原农田均衡发展的关键。
农田集约化与农业生态系统服务的耦合协调程度从基本协调到严重不协调。因此,应优化该地区的农田集约化措施,以提高这种协调程度。从2000至2020年,耦合协调度也呈上升趋势。退耕还林工程中边缘耕地的减少是造成这一趋势的重要原因之一,特别是在北方地区。83.6%左右的高—高聚类点集中在黄土高原南部,70.5%左右的低—低聚类点分布在黄土高原北部。这些分异特征主要与这些地区的农业环境适宜性和经济发展程度有关。
据悉,农业生态系统面临的最大挑战之一,是在保持农业生态系统服务的同时改善耕地集约化。虽然已有许多研究调查了农田集约化对农业生态系统服务的影响,但这些因素之间的相互耦合和协调在很大程度上仍未得到探索。

Abstract: One of the greatest challenges in the agroecosystem is to improve cropland intensification while preserving agroecosystem services. While many studies have investigated the effect of cropland intensification on agroecosystem service, the interactive coupling and coordination among these factors remain largely unexplored. In view of this, this study performed a case study of the Loess Plateau in Shaanxi Province, China and constructed comprehensive evaluation models to quantify the cropland intensification and agroecosystem service in this area. Balance analysis and the coupling coordination degree model were used to evaluate the interactive relationship between cropland intensification and agroecosystem service, and statistical analysis and spatial autocorrelation were used to analyze the spatial characteristics and potential mechanism of the coupling coordination. Results show that both the cropland intensification and agroecosystem service in the study area were relatively low yet gradually increased from 2000 to 2020. Agroecosystem service lag was identified as the dominant unbalanced development type. Improving the supply capacity of agroecosystem services plays a key role in the balanced development of cropland in the Loess Plateau. The coupling coordination degree between cropland intensification and agroecosystem service ranges from basic coordination to serious incoordination. Therefore, cropland intensification practices in the area should be optimized to enhance this coordination degree. An upward trend was also observed in the coupling coordination degree from 2000 to 2020. The withdrawal of marginal cropland in the Grain for Green program is one of the most important reasons for this trend, especially for the northern region. Around 83.6% of the high-high clusters are concentrated in the southern region of the Loess Plateau, whereas 70.5% of the low-low clusters are distributed in the northern region. These clustering characteristics are mainly attributed to the environmental suitability of these areas for agriculture and their degree of economic development.
