“…Furthermore, PLS-PM is reported to be a soft modeling method applied to model fundamental paths among blocks of parameters 44 . It is preferred by different researchers as it is simple with no strong assumptions regarding the sample size, distributions, and the estimation scale requirement 45 . Its application in this study eased the estimation of the complex cause-effect correlation among LULC variables, water quality parameters in both seasons, and the NSF-WQI values.…”

Understanding the influence of land use/land cover (LULC) on water quality is pertinent to sustainable water management. This study aimed at assessing the spatio-seasonal variation of water quality in relation to land use types in Lake Muhazi, Rwanda. The National Sanitation Foundation Water Quality Index (NSF-WQI) was used to evaluate the anthropogenically-induced water quality changes. In addition to Principal Components Analysis (PCA), a Cluster Analysis (CA) was applied on 12-clustered sampling sites and the obtained NSF-WQI. Lastly, the Partial Least Squares Path Modelling (PLS-PM) was used to estimate the nexus between LULC, water quality parameters, and the obtained NSF-WQI. The results revealed a poor water quality status at the Mugorore and Butimba sites in the rainy season, then at Mugorore and Bwimiyange sites in the dry season. Furthermore, PCA displayed a sample dispersion based on seasonality while NSF-WQI’s CA hierarchy grouped the samples corresponding to LULC types. Finally, the PLS-PM returned a strong positive correlation (+ 0.831) between LULCs and water quality parameters in the rainy season but a negative correlation coefficient (− 0.542) in the dry season, with great influences of cropland on the water quality parameters. Overall, this study concludes that the lake is seasonally influenced by anthropogenic activities, suggesting sustainable land-use management decisions, such as the establishment and safeguarding protection belts in the lake vicinity.

Tourism has developed into an industry with a powerful momentum of development in the world today. With the development of information technology, information has become a powerful driving force to promote the prosperity and development of the tourism industry and the entire society. The introduction of the tourism information system can significantly improve the service level, operation level, and management level of the tourism industry, thereby accelerating tourism development. The research of this article is to help villages establish a set of MVC-based rural tourism information service systems that can promote the development of rural tourism. First of all, this article conducts demand research on tourists, rural scenic spots, and ancient villages to discover the problems in rural tourism development. Secondly, this paper combines the problems existing in constructing the various subsystems of the rural tourism information system, combined with the fuzzy comprehensive evaluation method. In this paper, we propose the rural tourism system architecture based on MVC. The system architecture consists of the user layer, service layer, business layer, and data layer. It describes the system’s implementation process from two aspects: the system’s interface design and its deployment model. Finally, the network topology structure of the rural tourism information service system based on MVC is drawn. Finally, the system’s deployment is implemented according to the network topology structure.

Interactions between pollution sources, water contamination, and ecological integrity are complex phenomena and hard to access. To comprehend this subject of study, it is crucial to use advanced statistical tools, which can unveil cause-effect relationships between pressure from surface waters, released contaminants, and damage to the ecological status. In this study, two partial least squares-path models (PLS-PM) were created and analyzed in order to understand how the cause-effect relationships can change over two seasons (summer and winter) and how the used scale (short or long) can affect the results. During the summer of 2016 and winter of 2017 surface water parameters and the North Invertebrate Portuguese Index were measured in strategic sampling sites. For each site, it two sections were delineated: the total upstream drainage area (long scale) and 250 m (short scale). For each section, data of pressures in surface waters including point source, diffuse emissions and landscape metrics were gathered. The methodology was applied to the Sabor River Basin, located in the northeast of Portugal. In this study, it was possible to determine in which season pressures affect ecological integrity and also which scale should be addressed. The models showed the influences of manganese and of potassium concentrations in stream water on the decrease in summer water quality, while arsenic’s harmful effect occurs during winter. Pastures and environmental land use conflicts were considered threats to water quality when analyzed on a long scale, whereas agricultural areas played a role when the short scale was used. The effect of landscape edge density revealed to be independent of scale or season. Effluent discharges in surface water affected the water quality during the summer season, while the effect of discharges in groundwater affected the water quality in winter. It has also been found that, to find the harmful effect of pressures, it is necessary to approach different scales and that the role of landscape metrics can also overlap contaminant sources.
