Spatiotemporal characteristics analysis of multifunctional cultivated land: A case‐study in Shenyang, Northeast China

Abstract

The configuration of multifunctional cultivated land is critical for its protection. Although studies on multifunctional cultivated land have been conducted, there is a lack of information regarding the spatiotemporal characteristics and tradeoff synergy relationship of cultivated‐land functions at the same time on a nonadministrative unit scale. The purpose of this study was to analyze the spatial distribution characteristics and the tradeoff synergy areas from the perspective of multifunctional cultivated land for efficient use of land resources to minimize the conflict between people and nature. The fuzzy optimization model and spatial autocorrelation analysis method were used to study spatial distribution characteristics and the tradeoff synergy spatial patterns, respectively. The results showed that (a) the implementation of different improvement measures for the spatial distribution characteristics of cultivated‐land functions could also accelerate the coordinated development of cultivated‐land functions, (b) multiple functions of cultivated land not only had a synergy trend in time, but they also had a heterogeneity and fluctuation in spatial distribution, providing a direction for the new development or management pattern of cultivated land, and (c) results on the multifunctional evaluation and tradeoff synergy relationship of cultivated land provided the foundation for determining the short‐board function and upgrading direction of cultivated land. At the grid scale, the evolution of functional distribution characteristics and functional relationships are helpful for decision‐makers to implement accurately farmland protection policies and formulate farmland regulation rules.

Spatiotemporal Patterns of Cultivated Land Quality Integrated with Multi-Source Remote Sensing: A Case Study of Guangzhou, China

“…Previous studies have found that the slope is closely related to CLQ; that is, the greater the slope, the worse the CLQ [30]. Moreover, topsoil texture (0-30 cm) is most relevant to soil quality and crop growth, which is widely used in many previous CLQ evaluation studies [11,40]. If the slope is smaller and the topsoil texture is fine, then the natural conditions of the cultivated land are better.…”

“…It is crucial to reveal the spatiotemporal changes in the CLQ and to identify its main influencing factors to improve CLQ [11,39]. Qian et al [40] revealed the spatiotemporal characteristics of the production function, ecological function, and social function of the cultivated land in Shenyang city. However, its spatial resolution was low (10 × 10 km), resulting in the spatial details of CLQ being poorly displayed.…”

Spatiotemporal Evolution of Non-Grain Production of Cultivated Land and Its Underlying Factors in China

“…However, owing to the profit-seeking nature of industrial and commercial entities, under the guidance of economic interests, the tendency of new agricultural business entities toward NGP is particularly strong. Therefore, driven by rapid urbanization, industrial and commercial capital cannot achieve the original intention of revitalizing the countryside, but instead exacerbate the NGP situation of the planting structure [5,[50][51][52][53][54][55].…”

Simulation of Policy Tools’ Effects on Farmers’ Adoption of Conservation Tillage Technology: An Empirical Analysis in China

“…In 2017, there were 0.43 million farmers. There are some problems in this area, such as a shallow farming layer, soil hardening, a decline in organic matter content, and so on [48]. The above areas are suitable for the implementation of CTT.…”
