An improved minimum cumulative resistance model for risk assessment of agricultural non-point source pollution in the coastal zone
TLDR
In this paper , a new minimum cumulative resistance to agricultural non-point source pollution (AGNPSP-MCR) model is proposed to simulate the transport process of cropland NPSP into the sea based on the "source sink" theory in landscape ecology.About:

The Eco-Agricultural Industrial Chain: The Meaning, Content and Practices
TL;DR: In this article , the authors proposed an eco-agricultural industrial chain, integrating a whole circular system with different sessions of crop farming, animal breeding, agricultural product processing, and rural living, was put forward to control the agricultural non-point pollution and protect the water environment systematically for the first time.

Applying water environment capacity to assess the non-point source pollution risks in watersheds.
TL;DR: In this article , the authors proposed a new NPS pollution risk assessment method that integrates water functional zoning, receiving water body environmental capacity, and space-time distribution of pollution load for quantifying the impact of pollution discharge from sub-catchment on nearby water body quality.

Suitability Analysis of Water Cultural Heritage Structures in Beijing Based on Analytic Hierarchy Process and Geographic Information Systems
TL;DR: Wang et al. as mentioned in this paper used the analytic hierarchy process (AHP) and geographic information systems (GIS) to develop a multidimensional evaluation system for water cultural heritage (WCH) structures based on the suitability perspective.

TL;DR: In this article, the seasonal flux of sediment, on a river-by-river basis, under modern and prehuman conditions, is provided, and the authors show that humans have simultaneously increased the sediment transport by global rivers through soil erosion (by 2.3 ± 0.6 billion metric tons per year), yet reduced the flux reaching the world's coasts (by 1.4 ± 0 3 billion metric ton per year) because of retention within reservoirs.

Spatial, sources and risk assessment of heavy metal contamination of urban soils in typical regions of Shenyang, China
TL;DR: The values of pollution index and integrated pollution index indicated that metal pollution level was Pb>Cd>Zn>Cu, and Cd, Cu, Pb and Zn belong to moderate or high pollution level, and Shenyang was suffering from serious metal contamination.

TL;DR: In this article, a combination of water-quality observations and simulated nitrogen discharge from agricultural and other sources was used to estimate spatial patterns of nitrogen discharge into water bodies across China from 1955 to 2014.

Spatial prediction and ordinary kriging
TL;DR: In this paper, the authors consider the assumptions needed to carry out the spatial prediction using ordinary kriging, and look at how nugget effect, range, and sill of the variogram affect the predictor.

Agricultural non-point source pollution in China: causes and mitigation measures.
TL;DR: The main causes for NPS pollution were excessive inputs of nitrogen fertilizer and pesticides, which were partly the result of the inadequate agricultural extension services and the rapid expansion of intensive livestock production with little of waste management.
