“…Nitrate nitrogen concentrations fluctuated highly on the Sebránek stream in 2014/2015 and ranged from 2.5 to 7.6 mg•dm -3 [MATALOVÁ 2015].One way to reconcile agricultural activities and water protection is to change the conventional way of farming to organic. This management regime has proved to be functional in a number of European catchment areas[Barataud et al 2014;Garnier et al 2014;Dumbrovský et al 2015].The results show that the concentration of total nitrogen in the Úmoří are strongly affected by its tributaries (SP 5 and SP 7). These flow into the Úmoří downstream from sources of drinking water, therefore the quality of drinking water is not affected by these tributaries.…”

The ground source of drinking water for the village of Skalice nad Svitavou is located 35 km North of Brno (Czech Republic). An evaluation of developments in selected indicators of water quality in this groundwater source in the period 2013-2017 was the essence of this work. The data was provided by Vodárenská akciová společnost, a.s., i.e. the operator. At the same time, annual monitoring of water quality in the Úmoří stream, which flows through the catchment area and can affect the quality of groundwater, was carried out. Water samples were collected in 2017-2018 from 6 profiles on the Úmoří stream and its two tributaries. Raw water from the groundwater source does not meet the requirements for drinking water in some indicators and needs to be treated. Monitoring of surface water shows that the most problematic indicator is total phosphorus, the concentration of which exceeded limit values on all sampling profiles. The highest values were found in the tributaries, where total phosphorus concentrations exceeded 10 mg•dm -3 . There are 12 municipalities in the area of interest, only two of which have their own sewage treatment plant. It is clear from the results that wastewater in some municipalities is discharged directly into the recipient and is the cause of above-limit concentrations of both phosphorus and nitrogen. Intensively used agricultural land is another major source of pollution. Based on an analysis of sources of pollution, corrective measures have been proposed to improve the quality of surface and groundwater in the area.

“…Now, the international community pays more attention to the research on new areas of land consolidation such as landscape design, environmental management and water and soil protection [ 25 ]. Many countries and regions mainly focus on water and soil erosion, landscape function decline, land degradation and other issues [ 26 , 27 ]. Based on the research on farmland protection, water and soil conservation and landscape restoration technologies and their ecological environmental effects emphasize the overall promotion of various projects in the land consolidation area [ 28 , 29 ], regarding ecological consolidation as a necessary means to maintain the sustainable development of the consolidation area, while emphasizing the accumulation and progress of multiple goals in land consolidation, such as ecological remediation, natural landscape design, cultural landscape protection and inheritance [ 30 , 31 , 32 ].…”

The functional zoning of land comprehensive consolidation and the selection of consolidation paths are the key content of the current land and space planning, and it is also an important measure to achieve regional sustainable development. At present, the research system on land comprehensive consolidation is not yet mature. The previous research area is relatively small and not representative, and an effective method system has not been formed. Research on the selection of functional zoning and a consolidation path is also relatively scarce. There is an urgent need to construct the theory and method system of land comprehensive consolidation functional zoning and consolidation path selection. Taking Dongying City in China as an example, this paper constructs a zoning index system from four aspects including natural conditions, location advantages, social economy and land use. The entropy method is used to determine the weights, and GIS spatial data visualization is used to analyze the spatial distribution characteristics of the index system. Based on the analysis, the grey constellation clustering method is used to divide the study area into four types of land comprehensive consolidation functional areas, and the results of functional zoning are adjusted according to the ranking of comprehensive index values, the principle of maximum similarity, and the continuity of natural space. The research results show that: ① There are 10 functional zonings for urban development and ecological protection land consolidation, and the main consolidation path should be the ecological country park consolidation model, which can effectively serve the urban ecological construction. ② There are nine functional zonings for rural development and cultivated land conservation consolidation, and their consolidation path should be based on a comprehensive rural improvement model that enhances the quality of the village and the development, utilization and protection of cultivated land resources. ③ There are 18 functional zonings for cultivated land improvement and ecological protection land consolidation, and the main consolidation path should focus on the cultivated land ecological improvement mode that emphasizes the quality of cultivated land and the improvement of regional ecological functions. ④ There are four functional zonings for ecological conservation and fallow recuperative land consolidation, and their main consolidation path should be the land ecological restoration and improvement model of construction land reclamation, cultivated land ecological conservation, and conversion of farmland to forest and grassland. The research results can provide references for Dongying City to formulate land and space planning, and can be extended to the design of comprehensive land remediation projects in other regions. It is of great significance to promote regional sustainable and scientific development.

“…The agricultural landscape is no longer able to contain more rainfall due to long-term management and destabilisation of the ecological balance (Olson et al 2017). In such cases, biotechnical or biological measures must be implemented, which can help to increase the retention of the water in the landscape, to regulate the outlet of the rainfall water through critical profiles and contribute to the overall stabilisation of the water regime (Dumbrovský et al 2015). Such elements include, in particular, water reservoirs with a retention function, including the accompanying vegetation and ground shaping.…”

The paper deals with the analysis of a river’s regime of a small watercourse and the evaluation of its changes after the construction of a small water reservoir. The aim of the work was to analyse 12 years of flow rate measurements at two profiles of a small watercourse, between which a small water reservoir was built, in the middle of the period of the measurements. The analysis uses traditional characteristics (average flow rate, discharge volume), as well as modern indices from applied hydrology (Richards-Baker flashiness index, hydrogram pulse analysis), which study the variability of the flow rate in hourly and daily intervals. The evaluation showed that at the average flow rate, the effect of the water reservoir was the smoothening of the peak flow rates and prolonging the duration of the discharge waves. At higher flow rates, the water reservoir causes a delay in the culmination and in terms of discharge balance causes a decreased discharge volume, in particular during the vegetation period.
