Improvements in vegetation coverage are driven by both resource endowment conditions and policy behaviors. To accurately reflect the restoration effect after ecological policies, this study used potential realization model to calculate degree of on Loess Plateau assess Grain for Green Program from 2000 2020. Then, influencing factors were explored using spatial Dubin model. The results reveal that (1) EVI value northern Shaanxi increased below 0.25 at beginning approximately 0.35 end,...

Quantifying the dynamic changes and relationships between ecosystem services (ESs) land use change is critical for sustainable management optimization. However, comprehensive discussions on spatiotemporal variations of ESs their with intensity (LUI) are lacking, particularly in context significant climate warming. Systematic analyses forestry unit scale limited, leading to considerable uncertainty management, especially alpine ecosystems Northern Hemisphere, where have significantly...

Financial returns of forest plantations are an important concern around the world. In this research, we focused on South China's timber investments, collected data from Pingxiang, Guangxi Province, China, which is demonstration zone Fast-growing and High-yielding Timber Plantation Base Construction Program National Strategic Storage Production Bases Program, used capital budgeting analysis method sensitivity to compare different scenarios planted management. The results showed that excluding...

Based on the pilot ecosystem analysis of Qianjiangyuan National Park, services function value index system was determined; multiple methods such as market method and shadow engineering were used to evaluate four major categories in years 2005, 2010, 2015, 2018 ecological national park which are provision, regulation, culture, support. Results show that total had increased 7430.11 × 106 yuan, 9128.41 12,718.38 15,539.99 yuan for each category respectively. The regulation has always been core...

Understanding the effects of landscape greening pest control modes (LGPCMs) on carbon storage and soil physicochemical properties is crucial for promoting sustainable development urban greening. Climate change green have led to increased occurrences. However, impacts different LGPCMs remain unclear. We examined six typical employed in Beijing, China: chemical (HXFZ), enclosure (WH), light trapping (DGYS), biological agent application (SWYJ), natural enemy release (SFTD), trap hanging...

To achieve sustainable ecosystem management, it is necessary to understanding the complex relationships among multiple services (ESs), especially in alpine ecosystems of Northern Hemisphere where ESs have undergone significantly degradation. Therefore, a comprehensive exploration must be performed, from time and spatial scales perspectives, into spatio-temporal changes different under climate warming. We selected Daxing'anling forest area, Inner Mongolia (DFAIM), which both sensitive, an...

Accurately assessing tree mortality probability in the context of global climate changes is important for formulating scientific and reasonable forest management scenarios. In this study, we developed a climate-sensitive individual model Masson pine using data from seventh (2004), eighth (2009), ninth (2014) Chinese National Forest Inventory (CNFI) Hunan Province, South–Central China. A generalized linear mixed-effects with plots as random effects based on logistic regression was applied....

Quantification of soil water-physical properties and their spatial variation is important to better predict structure functioning, as well associated patterns in the vegetation. The provision site-specific data further facilitates implementation enhanced land use management practices. Using geostatistical methods, this study quantified distribution bulk density (SBD), moisture (SM), capillary water-holding capacity (CWHC), porosity (CP), non-capillary (NCP), total (TP) southern subtropical...

Establishing monoculture of native broadleaved tree species and mixed coniferous plantations is the tendency for forest management in subtropical China. The variations structure function soil bacterial community are still not clear. We examined under different layers (0-20, 20-40 40-60 cm) three planted forests, including Castanopsis hystrix, Pinus massoniana their plantation, south China, using 16S rRNA gene high-throughput sequencing PICRUSt prediction. results showed that plantation P....

To accurately assess carbon storage and its spatial distribution in natural secondary forest at the regional scale, we constructed seven expansion models by modifying geographically weighted regression (GWR) aspects of dimension, parameter heterogeneity residual autocorrelation, based on data collected from 165 bureau level permanent plots Langxi Forest Farm Wangqing Forestry Bureau Jilin Province. Stand factor, topography soil factor were selected as influencing factors. The included...

Larix gmelinii natural forests, which are of great ecological and economic importance, mainly distributed in northeast China. Sustainable management these forests play a vital role security China, especially the context climate change. Forest growth models, support forest decision-making, lacking for hampering prescription strategies. In this study, we produced climate-sensitive, transition-matrix model (CM) forests. For comparison, variable transition without including change effects (NCM)...
