Population growth and rapid economic development have led to serious widespread negative ecological impacts, so the world is faced with task of recovery. China, in particular, carrying out a nationwide land improvement restoration campaign. The spatial distribution resilience needs be fully considered planning these projects. However, most current assessments lack focus on resilience. Based selected principles, this paper constructs an assessment indicator system for national-scale...

Land utilization transformation (LUT) is a key factor affecting ecosystem services (ESs). The urban agglomeration on the Northern Slope of Tianshan Mountains (UATM) located in typical arid region with extremely fragile ecological environment. However, impact LUT spatial pattern ESs over past 20 years not clear. This study aimed to explore characteristics UATM using land transfer matrix, information entropy, intensity, and dynamic degree. Various indexes were quantitatively measured...

Waste pickers (WPs) play an indispensable role by helping to control municipal solid waste (MSW). However, they constitute the entry-level workforce of recycling industry and receive little attention from general public. In China, approximately 4 million WPs make their living collecting MSW recyclable materials. To assess WPs, extensive social survey including urban management decision-makers, industrial circle insiders, as well common citizen respondents has been conducted in city Nanjing,...

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...

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...

ABSTRACT Rapid global urbanization had significantly altered land use (LU), threatening the ecology and sustainability of arid regions. Systematic forward‐looking analyses changes (LUCs) ecological risks in Asia's zones, particularly urban agglomeration on northern slope Tianshan Mountains (UANSTM), remained limited. Herein, LUCs UANSTM under four scenarios, including ecology‐economy balanced development scenario (EES), protection (EPS), economic (EDS), natural (NDS) 2030, was predicted by...
