The value of a cultural ecosystem service depends on the perception different categories. However, data sources used in research have limitations that mainly depend social investigation, leading to slow progress evaluation. With advent era network big data, media provides new source for study perception, so these services is expected make breakthroughs. Using search crawler software, this paper reviewed 7257 online comments related 19 city parks Xuzhou City, China. help Rost Content mining...

Understanding the changes in a land use/land cover (LULC) is important for environmental assessment and management. However, tracking dynamic of LULC has proved difficult, especially large-scale underground mining areas with extensive heterogeneity history multiple disturbances. Additional research related to methods this field still needed. In study, we tracked change Nanjiao area, Shanxi Province, China between 1987 2017 via random forest classifier continuous Landsat imagery, where years...

Visible and near infrared spectroscopy is an effective method for monitoring the content of heavy metals in soil. However, due to difference between polluted soil with phytoremediation without phytoremediation, common estimation model cannot meet accuracy requirements. To solve this problem, combined ecological restoration experiment contamination using plant Neyraudia reynaudiana, study explored feasibility a hyperspectral technology estimate metal (Cd, Cr, Pb) under phytoremediation. A...

The concept of high-quality development has become the current theme China’s economic construction. High-quality requires maintaining a healthy and cyclical approach to development, which is challenge in original approach. Yet, great deal evidence suggests that there strong interrelationship between ecological environment, developing method quantify this important for studying extent development. Here, we propose new indicator system using coupling degree model coordination assess coupled...

Remotely sensed images with low resolution can be effectively used for the large-area monitoring of vegetation restoration, but are unsuitable accurate small-area monitoring. This limits researchers’ ability to study composition species and biodiversity ecosystem functions after ecological restoration. Therefore, this uses LiDAR hyperspectral data, develops a hierarchical classification method classifying based on technology, decision tree random forest classifier, applies it eastern waste...

Improvement of soil quality after land reclamation is a key concern in mining areas. However, the characteristics and internal mechanisms variation bacterial community structure over different periods are currently unclear. The recovery evolution microbial important indicators level improvement reclaimed soil. Therefore, this study investigated samples from coal gangue-filled 1, 6, 15 years. To accomplish this, 16S rRNA gene libraries were produced to determine composition soils. In...

Participants in the land market are usually hampered to browse and analyze price information due lack of sources available analysis tools. A service-oriented GIS-based web system was developed provide a practical solution, its essential data contain basic geographic elements benchmark (BLP)-related information. Core models for were implemented, including index, spatial distribution, parcel appraisal. The based on four-level Browse Server (B/S) architecture using GIS service technologies,...

This work investigated the spatial profile and source analysis of polycyclic aromatic hydrocarbons (PAHs) in soil that surrounds coal-fired power plants Xuzhou, China. High-throughput sequencing was employed to investigate composition structure bacterial communities. The total concentration 15 PAHs surface soils ranged from 164.87 3494.81 μg/kg dry weight. site-specific with a 1400.09-3494.81 Yaozhuang. Based on qualitative principal component results, coal burning vehicle emission were...

We explored the characteristics of soil bacterial communities and their ecological functions under different types vegetation reclamation in open-pit mines on Loess Plateau, which is guiding significance for selection improvement restoration effect mining areas. The research object was to reclaim aluminum mine waste dump Xiaoyi County, Shanxi. were measured reclamation. community using 16S rRNA gene high-throughput sequencing technology. function predicted PICRUSt method. correlation between...

Land consolidation of dryland-to-paddy conversion for improving tillage conditions and grain production capacity is widely implemented throughout the world. The affects soil ecological stability, especially most active microorganisms. However, impacts has paid little attention in recent decades. In this study, a pot experiment was used to explore responses microbial community their interactions with properties after rice first season (five months). results indicated that significant decrease...

The ecological rehabilitation of potential toxic metal-contaminated soils in sites disturbed by mining has been a great challenge recent decades. Phytoremediation is one the most widely promoted renovation methods due to its environmental friendliness and low cost. However, there lack situ investigation on influence vegetation pattern spontaneous succession metal-polluted soil. To clarify how early stage restoration remediation soil, we investigated metal dump Sichuan, China, field...

As an essential ecological parameter, soil moisture is important for understanding the water exchange between land surface and atmosphere, especially in Loess Plateau (China). Although Synthetic Aperture Radar (SAR) images can be used retrieval, it still a challenge to mitigate impacts of complex terrain over hilly areas. Therefore, objective this paper propose improved approach estimation gully fields based on joint use Advanced Integral Equation Model (AIEM) Incidence Angle Correction...

Wetlands provide many essential ecosystem services for human well-being. The ecological assessment of wetland is problematic and thus an important focus in the field research. In this study, system containing product value, regulation service cultural value was established to calculate gross Nansi Lake Wetland, China. Based on remote sensing images, studies, literature reviews, estimated years 1985, 1992, 2005, 2011, 2017. results showed that Wetland increased from 40.91 × 108 USD 1985 46.28...

Soil microorganisms play a key role in global biogeochemical changes. To understand the interactions among soil bacterial communities and their responses to extreme environments, properties community diversity were determined post-mining ecosystem of Loess Plateau, China. The results showed that temperature, pH, organic matter, available phosphorus, potassium values significantly reduced cracks area. However, richness uniformity increased by about 50% microbial structure network tended be...
