Land transformation during global urbanization has led to a sharp decrease in farmland, causing not only food security issues but also ecological problems. To address this issue, the Chinese government implemented Requisition-Compensation Balance Policy for Farmland (RCBF) 1997. This policy effectively curbed reduction of compensated land often comes from mountainous and desert areas, leading fragmentation farmland subsequent issues. The balance between requisition compensation is closely related security. However, current research on occupation mostly based area. area occupied by different regions inconsistent, using net increase or represent cannot accurately fairly compare degree regions. Therefore, study proposed novel index measure compensation-the Requisition Compensation Index (FOCI). FOCI can transform dimensional expressions that into dimensionless expressions, namely scalars, which makes it possible visually each region. Then, new been used investigate spatiotemporal evolution China at national provincial levels over past 30 years (1990-2021), as well impact change landscape service value. results indicate (1) shows trend first decreasing then increasing both scales; (2) Provinces with are mainly concentrated southeast northwest regions, while significant decreases observed southwest region, indicating shift center gravity towards southeast; (3) significantly positively correlated spatially, suggesting provinces higher exhibit fragmentation; (4) value negatively have lower values, these areas region China. In general, advantage eliminating influence could be reliable alternative evaluating

Crop straw—a carbon-neutral bio-based resource—is gaining attention because of its scalable and sustainable conversion utilization modes amid the coordinated pollution control carbon reduction efforts. Building on prior research with limited scope, this study introduces a multidimensional evaluation framework for spatial suitability encompassing entire chain crop straw resources. The intertwines heterogeneity multiple resources, transcending limitations single focus by evaluating three major simultaneously. In China, distribution characteristics potential resources at provincial level have stabilized over time. are concentrated in provinces North Northeast Middle-lower Yangtze River agricultural region, where proportion flat cultivated land area is higher than 78% total area, wide concentrated. Their annual collectable generally exceeds 50 Mt. Spatial reveals that twelve provinces, including Beijing, suitable promoting fertilizer utilization, eight such as Inner Mongolia, feed ten Henan, energy utilization. Overall, informs policymakers optimization strategies high-quality efficient

Urban development inevitably comes with the loss of prime agricultural land, leading to a decline in cropland productivity. The Northeast region is an important grain-producing China, and land great significance ensuring national food security. Here, use cover data MODIS-NPP were used comprehensively understand direct adverse influence urban growth on net primary productivity (NPP) China. results indicated that (1) area increased by total 5230.00 km2 since 2000. phenomenon was particularly notable cities near central transportation trunk line along southern coastal regions. (2) more than half newly added patches originated from cropland. Between 2000 2020, expansion China resulted 0. 85 Tg C NPP. (3) there significant regional variation NPP loss. low altitude slope regions experienced most Meanwhile, large developed caused losses, dispersed had broader impact concentrated expansion. (4) when converting crop yield, it revealed reduction 0.91 million tons grain yield These findings provide valuable insights for protection strategies offering crucial guidance sustainable practices.

Carbon storage plays an important role in the global carbon cycle and climate change mitigation. Understanding relationship between land use can significantly contribute to neutrality sustainable development. However, most previous studies only analyze due change, while few quantitatively evaluate contributions of various transitions (LUTs) which cannot provide enough information for management. In context rapid urbanization ecological conservation, Poyang Lake basin (PYLB) has experienced dramatic affected local storage. Therefore, this study used InVEST model PYLB from 1990 2020. Then, Geo-information Tupu method was quantify LUTs identify key LUTs. The results showed that decreased by 17.26 Tg gain mainly attributed ‘farmland forestland’ (36.87%), ‘grassland (22.58%), water’ (15.89%). contrast, built-up land’, ‘forestland grassland’ contributed 39.94%, 28.06%, 13.25% loss, respectively. Massive loss caused expansion should attract attention. This references formulation optimization policies achieve development PYLB.

With the rapid development of urbanization and industrialization, rural functions in China's mountainous regions have tended to diversify, use sloping cultivated land has also evolved. Exploring coupling relationship between functional diversification evolution is great significance protection areas sustainable villages. We constructed a theoretical framework analyze interaction then verified it with Fengjie County, China. Our research results show that: overall agricultural production function, industrial leisure tourism social security ecological conservation function County continue develop, level been enhanced. The high density value were more dispersed, area showed decreasing trend. coordination degree gentle downward trend, economic decreased. steep sharp firstly increasing two kinds increased. study can be summarized into four modes different strategies should adopted for modes. These methods findings provide reference optimal utilization resources other areas.
