The article presents the analysis of the current situation of the forest area in Alytus and Vilnius Counties. Comparative, analytical as well as statistical and logical analysis methods were used for the investigation. The aim of the investigation is to carry out the analysis of the Alytus and Vilnius Counties forest area during the period between the years 2006 and 2018. The object of the investigation – Alytus and Vilnius Counties forest area. Tasks of the investigation: 1. To describe the status quo of forest in Alytus and Vilnius Counties. 2. To analyze and compare the forest area change in Alytus and Vilnius counties during the period between the years 2006 and 2018. The study found that forests prevailing in Alytus and Vilnius Counties are 50–59 years old. It was determined that pine trees prevail in Alytus County (71.05 percent) and in Vilnius County (16.38 percent) as well. The type of ownership prevailing in both Alytus and Vilnius counties is the forests of state significance managed by forest enterprises, national parks and state reserves. In Alytus County, during the period between the years 2006 and 2018, the forest area decreased by 4123.16 ha or 1.55 percent, in Vilnius County increased by 9593.16 ha or 2,35 percent.

The main purpose of data mining in private and public sector institutions is to process and analyse data with the aim of generating reliable information for decision-making. Decision-making performance is determined by the availability of the relevant data and the user’s ability to adapt that data for analytical purposes. The popularity of spatial statistical tools is on the rise owing to the complexity of the analysed factors, their variation over time and their correlations with the spatial structure. Popular models should be applied in demographic analyses for the needs of the spatial planning process. The availability of high-resolution data and accurate analytical tools enhances the value of spatial analyses, and the described models can be universally applied to support the decision-making process. The aim of this study was to present the applicability of selected spatial statistical models for analysing demographic data in the planning process and to identify the main advantages of these models.

The possibilities of using the geospatial analysis methods for visualizing land monitoring data and modelling the spatial distribution of the main agrochemical soil indicators are discussed in the article. The research was conducted within the limits of land use of RUP “Uchkhoz BGSHA” (Republic of Belarus, Mogilev region, Goretsky district). The total area of the surveyed territory was 3187.0 hectares. The geospatial analysis of the spatial distribution of humus, mobile phosphorus, mobile potassium and pHKCl was carried out using the Geostatistical Analyst module of the ArcGIS software. Semivariograms were used as the main tool for studying the structure of the spatial distribution of agrochemical indicators. The exponential function was identified as the best variogram model, the type of the circle was standard, the type and the number of sectors was 4 with a displacement of 450, and the lag was 200 metres. The interpolation accuracy was determined from the mean error (ME), mean square error (RMSE) and standard error (RMSS). The universal kriging method was used to perform the forecast and visualize the spatial distribution of agrochemical indicators. The multivariate analysis was performed using the functionality of the Raster Calculator tool, Principal Component analysis and Maximum Likelihood Classification. The search and determination of areas of sites with the most optimal agrochemical indicators were carried out by the multifactor analysis in the GIS environment. Calculation of the area of each circuit within the limits of working parcels was carried out using the utility "Zone Statistics".

2018
Ievsiukov, T., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine)
The main factors that influence the rational land use, conservation and protection of land resources are global ecological and food security, world's population growth, climate change, land acquisition by large world agricultural corporations etc. In this process a priority of attention is protection of the important agricultural lands (in Ukraine, these lands are called especially valuable lands - EVL). Besides, lands with highly productive soils, areas with undisturbed ecosystems, territories with objects of cultural heritage, natural therapeutic resources are a part of EVL. This paper focuses on new approaches to the legal protection of EVL in Ukraine. The special value of these lands in Ukraine is legalized and is means of their legal protection (Art. 150 of the Land Code of Ukraine). The main idea of this paper – studying of problems of legal protection of EVL and development of new approaches to their protection. These approaches will be based on introduction of economic regulators at withdrawal of EVL or change their intended use for needs that don't correspond to nature protection value. The reseach is based on case study method and statistical method. Approaches for cartographic modeling for assessment and mapping of EVL are offered. Results of this reseach are an obtaining of practical experience in the field of protection of EVL in Ukraine, development of suggestions for improving of an organizational and legal mechanism the use of EVL through their registration, monitoring, evaluation, development of their State Register. These measures can increase competitiveness of EVL, prevent Land-Grabbing and provide sustainable development of the rural territory.
