“…4) (Wang et al, 2014;Sawada et al, 2020). This is consistent with previous cluster analysis results, which showed that ower and vegetable cultivation with high fertilization increased the contribution of exogenous nitrogen to eastern Dianchi Lake (Huang et al, 2017a). The correlation between ON and the mid-and short-chain n-alkanes was most signi cant in DC-N, especially for C 17 (R 2 = 0.87).…”

“…Moreover, the construction land increased sharply from 137 km 2 (1995) to 842 km 2 (2012) in the Dianchi Lake basin (Fig. 5B), which was accompanied by a large amount of topsoil erosion due to the disruption of the Earth's surface (Guzman et al, 2013;Huang et al, 2017a). A previous study revealed that uvial sediment yield increased 1.85 times, as compared with the background value, because of the agricultural land use in western China's rivers (Schmidt et al, 2018).…”

The concentration and sources of organic nitrogen (ON) in lake sediment signi cantly affect the lake nitrogen cycle. However, the in uencing factors and contributors to the ON accumulation rate (ON AR ) are unclear. In this study, tree sediment cores from northern, eastern, and southern Dianchi Lake (DC-N, DC-E, and DC-S, respectively), sampled in July 2014, were used to study the effects of autochthonous and allochthonous sources on ON. The results showed that ON and the ON AR increased 2. 4-5.1 and 2.6-4.8 times, respectively, from1900 to2000, especially since the 1980s, at which point algal blooms occurred more frequently. The ON contents decreased in the order: DC-S > DC-N > DC-E, whereas the ON AR values followed the order: DC-N > DC-S > DC-E, suggesting that the ON AR was in uenced by ON content as well as depositional environmental conditions. The total concentrations of n-alkanes (n-C 12 to n-C 34 ) ranged from 4719.4 ng g − 1 to 61,959.6 ng g − 1 in the three sediment cores, each of which exhibited different n-alkanes characteristic variation with vertical depth. The sources of ON were mainly allochthonous (soil erosion and terrestrial plants) and autochthonous (algal and aquatic plants) in DC-S and DC-N, respectively, whereas they were primarily mixed planktonic and terrestrial sources in DC-E. Using the stochastic impacts by regression on population, a uence, and technology model to further examine the ON AR values revealed that 1% increase in temperature and nitrogen fertilizer can increase the ON AR by 73.8-86.2% and 73.2-151.3% in all sediments, especially in DC-S and DC-E. However, a 1% increase in construction area could reduce the ON AR by 2.4-14.2%, especially in DC-N. Overall, climate change and human activities determine the spatial and temporal ON AR variation in Dianchi Lake.

“…As two highly needed factors during the growth of cotton [51,52], mulching film and phosphorus fertilizer become the most significant input on arable land. Similarly, located in South China District, Yunnan enjoys subtropical monsoon climate with sufficient water-heat resources and fertile red soil, which makes ideal living environment for tobacco and sugar crops [53]. Potash fertilizer, the indispensable factor for tobacco and sugar crops, showed a growth rate with 7.5 times that of the average level in China.…”

In the rapid process of urbanization in China, arable land resources are faced with dual challenges in terms of quantity and quality. Starting with the change in the coupling coordination relationship between the input and output on arable land, this study applies an evaluation model of the degree of coupling coordination between the input and output (D_CCIO) on arable land and deeply analyzes the recessive transition mechanism and internal differences in arable land use modes in 31 provinces on mainland China. The results show that the total amount and the amount per unit area of the input and output on arable land in China have presented different spatio-temporal trends, along with the mismatched movement of the spatial barycenter. Although the D_CCIO on arable land increases slowly as a whole, 31 provinces show different recessive transition mechanisms of arable land use, which is hidden in the internal changes in the input–output structure. The results of this study highlight the different recessive transition patterns of arable land use in different provinces of China, which points to the outlook for higher technical input, optimized planting structure, and the coordination of human-land relationships.

“…For instance, the expansion of forest cover could strongly increase fire risks and limit the availability of pasture lands (Lasanta et al, 2018). We caution, however, that there are benefits from afforestation including reduced soil erosion (Huang et al, 2017;Porto et al, 2009), increased infiltration rates (Ilstedt et al, 2007) and increased biodiversity (Buscardo et al, 2008). Adoption of afforestation plans in abandoned areas, however, should balance these benefits with potential hydrologic impacts and consider alternative land management strategies.…”

Water resources availability is one of the main concerns for policy makers around the world in present and future management plans. In the Mediterranean basin, this concern is increased given the extreme variability in climate and the intrinsic aridity conditions. Water resources in the Mediterranean region depend mainly on surface and subsurface supply from mountain areas. Because evapotranspiration comprises a substantial portion of the water budget, recent land cover changes due to cropland abandonment may change transpiration (TRANS) and water supply. Therefore, land management plans must account for these potential hydrologic changes to guarantee water availability in the upcoming decades. Short-term changes to water yield have been shown to follow afforestation or natural revegetation, the main management strategies in abandoned cropland areas. Studies comparing long-term trends of these management practices, however, are scarce due to the lack of long-term hydrological data. In this study, we use the regional hydro-ecological simulation system (RHESSys), to analyse long-term changes and annual and seasonal trends in streamflow (STR) and transpiration following management of abandoned cropland areas. Annual mean values show significant differences between the three management scenarios for both streamflow and transpiration, while differences between climate scenarios are not significant. The Mann Kendall trend analysis shows significant changes to water yield compared to the situation before management. Depending on the total afforested area, afforestation could significantly decrease annual streamflow between 2.3%Ádecade À1 and 5.9%Ádecade À1 and increase annual transpiration between 1.1%Á decade À1 and 3.5%Ádecade À1 . These trends are attributed to changes during the first 30 years after management, while during the fourth and fifth decade, changes to water yield tend to stabilize or decrease. These results are substantial to optimize land management plans, ensuring sustainable hydrological and ecological ecosystem services.
