“…With progress being made in remote sensing and geographic information systems, hydrological models are increasingly employed to evaluate water-retention capacity. For example, scholars have used the Integrated Valuation of Ecosystem Services and Tradeoffs model (InVEST) (Yu et al, 2012;Pan et al, 2013;Bao et al, 2016), Soil and Water Assessment Tool model (SWAT) (Wang et al, 2010;Zhou et al, 2013;Hou et al, 2018b;Li et al, 2019a), and the Soil Conservation Service model (SCS) (Chen et al, 2017) to evaluate the water-retention capacity of important ecological reserves, such as the Loess Plateau, the Three-River Source region, the BTH region, and the Qilian Mountains. Simulations expand the spatial scale of traditional experimental observation and have been proved suitable for the estimation of water-retention capacity at large scales, with data relatively easy to obtain.…”

Water retention is important in forest ecosystem services. The heterogeneity analysis of water-retention capacity and its influencing factors is of great significance for the construction of water-retention functional areas, restoration of vegetation, and the protection of forest ecosystems in the Beijing-Tianjin-Hebei region. A total of 1366 records concerning water-retention capacity in the canopy layer, litter layer, and soil layer of forest ecosystem in this region were obtained from 193 literature published from 1980 to 2017. The influencing factors of water-retention capacity in each layer were analyzed, and path analysis was used to investigate the contribution of the factors to the water-retention capacity of the three layers. The results showed that mixed forests had the highest water-retention capacity, followed by broad-leaved forests, coniferous forests, and shrub forests. In addition, no matter the forest type, the ranking of the water-retention capacity was soil layer, canopy layer, and litter layer from high to low. The main influencing factors of water-retention capacity in forest canopy were leaf area index and maximum daily precipitation (R 2 =0.49), and the influencing coefficients were 0.34 and 0.30, respectively. The main influencing factors of water-retention capacity in the litter layer were semi-decomposed litter (R 2 =0.51), and the influencing coefficient was 0.51. The main influencing factors of water-retention capacity in the soil layer were non-capillary porosity and soil depth (R 2 =0.61), the influencing coefficients were 0.60 and Journal of Geographical Sciences 0.38, respectively. This study verifies the simulation of the water balance model or inversion of remote sensing of the water-retention capacity at the site scale, and provides scientific basis for further study of the impact of global change on water retention.

“…During the growth of crops in cultivated land, they fix CO 2 and release O 2 through photosynthesis, which plays a key role in regulating the carbon-oxygen balance in the atmosphere. Inverting the amount of CO 2 and O 2 released by the dry matter accumulated by crops in the process of light and action on cultivated land and then combining the cost of carbon sequestration and oxygen production to obtain the value of carbon sequestration and oxygen production services is a commonly used method in ecosystem service evaluation [45][46][47]. The calculation method is as follows:…”

The significant positive externality of cultivated land ecosystem services leads to the low comparative benefit of cultivated land utilization and then causes practical problems such as the abandonment and non-agriculturalization of the cultivated land, which poses a threat to China’s food security. The existing protection system only focuses on the quantity requirement and food production service of cultivated land and ignores the multi-function of cultivated land as an ecosystem, resulting in insufficient incentives and poor effect. Therefore, it is necessary to optimize the protection’s economic compensation standard by adding the cultivated land’s ecosystem service value in order to comprehensively assess cultivated land resources and correct for externalities. Taking the area around Hangzhou Bay, where the contradiction between cultivated land protection and economic development is prominent, as an example, the values of six typical cultivated land ecosystem services in 2016 was constructed and calculated, including food production, carbon sequestration and oxygen production, water conservation, soil conservation, biodiversity maintenance, and cultural leisure. Combined with ecosystem services’ values and the quality index, we finally determined the new county-level compensation standard of cultivated land protection in the Hangzhou Bay area. The results show that the value of cultivated land ecosystem services present obvious regional disparities, meaning that there exist significant differences in the sustainable use capacity of cultivated land and the necessity of establishing grading compensation standards in the region. Finally, we analyze the rationality and innovation of the new compensation standard model as well as its role in the protection of cultivated land and look forward to promoting the sustainable use of cultivated land through these new incentives.
