Research about farmland pollution by heavy metals/metalloids in China has drawn growing attention. However, there was rare information on spatiotemporal evolution and levels of metals the major grain-producing areas. We extracted examined data from 276 publications between 2010 2021 covering five regions to 2021. Spatiotemporal characteristics main obtained meta-analysis. In addition, subgroup analyses were carried out study preliminary correlations related accumulation pollutants. Cadmium (Cd) found be most prevailing pollutant terms both spatial distribution temporal accumulation. The Huang-Huai-Hai Plain severely polluted. Accumulation Cd, mercury (Hg) copper (Cu) increased 2015 when compared with 1990 background data. Further, key (Cd, Cu, Hg, lead [Pb] zinc [Zn]) showed increasing trends 2016 all regions. Soil pH mean annual precipitation had variable influences metal Alkaline soil areas less rainfall faced higher levels. Farmlands cropped mixed species smaller effect sizes than those single upland crop, suggesting that use patterns could alleviate soil. Of various remediation efforts, projects only held a small market share. findings are important support research risk assessment, regulatory development, prevention, fund allocation actions.

The "requisition-compensation balance policy" is a basic arable land protection policy promulgated by the Chinese government to maintain dynamic of total land. Since implementation policy", its important role in conservation has been widely noted. Multiple studies indicate effectiveness estimating quantity and quality change In addition, defects negative externalities are disputed. overall goal this study estimate provincial-level mainland China two periods (i.e., 2000—2010; 2010—2020) from four perspectives: balance; productivity farming distance; sustainability use. results showed that, first, was achieved during 2000–2020 national perspective. There still 19–23% provinces have failed reach balance. Second, decrease China's exacerbated 9612.1 thousand tons. 31254.6 ton. average potential yield index less than 1 for nearly all 2000–2010 became even worse next decade because occupying superior while compensating inferior become more quantity. Third, due lack constraints on distance changes most convert around urban rural areas built-up replenishing far residential without providing adequate agricultural infrastructure, which leads an increase cost consequently marginalization During 2010–2020, compensated at provincial level reached 2–7 times that occupied However, whole decreased 3.82–63.88% same period.

Fourth, percentage sustainable lower 70%. indicated utilization these insufficiently implemented monitored.

Systematically recognizing spatial patterns and driving factors of cultivated land fragmentation is great significance for the exploration locally appropriate path to relieve fragmentation. This study aims estimate density, mean patch size area-weighted shape index respectively indicate characteristics from three dimensions, namely, natural resource endowment, partition, convenience utilization. The regional leading are also analyzed. results demonstrate that distribution density higher in Northern regions compared with those southern regions. significant positive correlation between found be universal across nearly all cities, exceeding differences terrain, elevation, climate, soil, social economic condition. For cities part China, regular partitioned smaller blocks irregular ones; alternatively, intensive meticulous farming under small-scale agricultural operation leads clusters low - index. Random forest model explains impact on fragmentation, an explanatory power ranging 66% 95%. terrain factor emerges as primary driver negatively affecting density. Gross domestic product dominant a (p < 0.01) negative climatic zones. Terrain, gross population most important Rural development degree influences greatly instructive at national scale exploring barriers impede regionally scaled use.
