Abstract. Soil erosion, considered a major environmental and social problem, leads to the loss of soil nutrients degradation structure impacts plant growth. However, data on effects land use changes caused by vegetation restoration erodibility for different slope aspects are limited. This study was conducted detect response aspect in typical watershed northern agro-pastoral ecotone China. The following indexes were used determine improvement through weighted summation method: comprehensive...
Based on the goal of "dual-carbon" strategy, it is important to explore impacts land use change carbon stock and drivers spatial differentiation in Xinjiang. Here, we predicted types Xinjiang 2035 under different scenarios analyzed stock, which great theoretical practical importance for policy formulation, structure adjustment, neutrality target achievement The coupled PLUS-InVEST-Geodector model was used temporal patterns rapid development, natural change, arable protection, ecological...
Soil aggregation is a hierarchical and complex process mediated by both abiotic biotic factors, crucial for preventing erosion.This study aimed to providing new insights into the role of factors on soil amid various thinning intensities exploring mechanisms aggregation. A survey involving four treatments (T0: no thinning, T10: low-intensity T20: medium-intensity T50: high-intensity thinning) Pinus tabulaeformis plantation was conducted explore quantify significance selected effects using...
In order to understand the heavy metal pollution of industrial and mining area in northern Guangdong Province, topsoil samples (0-20 cm) from 209 sites study were collected, concentrations As, Cd, Cr, Cu, Hg, Ni, Pb, Zn analyzed. The source distribution characteristics soil analyzed using geographic information system (GIS) principal component analysis (PCA), geo-accumulation index potential ecological hazard used evaluate their status risk. results showed that:① Except all seven elements...
Slope length is an important topographic factor for controlling soil erosion. There exists limited knowledge of the interactions slope length, vegetation restoration, and rainfall intensity on This study investigated impact erosion different grass coverages intensities via simulated experiments. The experiments included five treatments (1, 1.5, 2, 2.5, 3 mm min−1), four cover (0%, 30%, 60%, 90%), (2, 4, 6, 8, 10 m). change process loss was significantly (p < 0.05) lengths. trend changing...
Abstract Soil organic carbon (SOC) plays a major role in maintaining long‐term ecological stability. This paper focuses on how land use conversion affects the stability of SOC (e.g., [C] molecular structure) and soil C cycle‐related enzyme activities are involved process. Four types around southern margin Qinghai Lake were researched: lakeside wetland, natural grassland, cropland, restored grassland. was dominated by O‐alkyl (O‐alkyl C, 40.6%–49.3% total intensity) alkyl (alkyl 25.9%–36.7%)...
Slope length is an important topographic factor for controlling soil erosion and pivotal parameters in the model. The impact of slope on was studied under different grassland rainfall intensity through simulated experiments. experiment included five treatments (1, 1.5, 2, 2.5 3 mm h−1), four grass cover (0, 30%, 60% 90%) (2, 4, 6, 8 10 m). results show that rate loss increased exponentially with increasing 0 30% cover. Under high covers (60% 90%), sedimentation from runoff reduced...
High nitrogen (N) and phosphorus (P) levels are the main causes of eutrophication water bodies, chemical oxygen demand (COD) is one indices relative organic matter content. Several simulated rainfall experiments have been conducted to investigate effects a single controlling factor on soil nutrient loss. However, role precipitation vegetation coverage in quantifying loss still unclear. We monitored runoff, loss, under natural conditions from 2004 2015 runoff plots around Beijing. Soil...
