Impacts of mechanized farmland transformation on ecological landscape patterns in hilly regions of Zhong County, China.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Ecological landscape patterns in agricultural areas are critical indicators of changes in ecological health and spatial structure in farmland utilization projects. In this study, the impacts of mechanized transformation on farmland ecosystems in Zhong County, Chongqing (2019-2024), were evaluated via remote sensing technology, landscape pattern indices, and Geographic Information System (GIS). A comprehensive assessment framework was developed across three dimensions: cropland quality enhancement, plot layout optimization, and topographic adaptation. The key findings included the following. (1) Mechanization upgraded 65.4% of inefficient farmland to high-standard agricultural land, significantly altering land use patterns. (2) Land use intensification increased markedly, with a 63.6% reduction in farmland patch number and a 64.3% decrease in patch density. Morphological improvements included an 18.8% decline in the landscape shape index (LSI) and a 37.3% reduction in edge density (ED). (3) Topographic simplification was achieved through reductions in slope complexity (6.1-18.9%) and elevation variation coefficients (2.96-6.28%). This research provides empirical evidence for optimizing ecological patterns through mechanization, and it offers actionable insights into sustainable agricultural development in hilly regions.
