Ecological and economic aspects of effective use of land resources – potential of Vinnytsia region

Hubar Yurii, Hulko Oleksandra, Khavar Yulia, Vynarchyk Liliya, Sai Vira

Geodesy and Cartography

2020

Vol. 69, no. 2

173--187

The article considers a comprehensive study of the problem of land relations development in the region. It identifies the main directions for their further development, which include improving the legislative framework, economic and monetary valuation of land, leasing land relations and ensuring the formation of a market for agricultural land and ecologically safe land use. The article aims to determine the interrelated components of the organizational and economic mechanism for managing land resources of agricultural enterprises in the context of ensuring land-use efficiency based on the choice of a land-use optimization model. The theoretical and methodological bases for the development of land relations in the conditions of market economy formation are generalized. The directions for improving the ecological status of agricultural land are justified. The state regulation of land relations is analyzed, and ways to improve land legislation are proposed. The directions of the formation and development of the agricultural land market are justified. The ways to improve the ecological condition of the land, taking into account the regional characteristics of the Vinnytsia region, are proposed. To determine the relationship of rational use and reproduction of resources, considering the problems of choosing the optimal strategy for the impact of the economy on the ecologization of land resources, the system of rational use and reproduction of natural resources is developed. The optimization model describing the conditions for the process of stimulating landowners and land users in the direction of protection and rational land use is established.

W celu określenia rodzaju gruntu poddano analizie rzeczywisty pomiar badania sondą statyczną z końcówką elektryczną CPTU. Wyniki analizy odniesiono do profilu geologicznego ustalonego na podstawie odwiertu wykonanego w odległości 5 m od miejsca sondowania. W niniejszym artykule do określenia rodzaju gruntu wykorzystano trzy klasyfikacje interpretacyjne wywodzące się z grupy drugiej: Robertsona i in. z 1986 r. [8], normową z PN-B 04452:2002 [4] oraz Robertsona z 1990 r. [11]. Uzyskane rozpoznania porównano oraz odniesiono do propozycji literaturowych ustalenia rodzaju gruntu na podstawie wskaźnika klasyfikacyjnego Ic [1, 2, 9, 10]

The values of qc, fs, u₂ measured during the examination using a CPTU probe may be used to determine numerous geotechnical parameters, such as the type of the subsoil and the soil profile. Numerous methods of classification of soil types can be found in the literature. Generally, these methods can be divided into two groups. The first group will include methods based on measurements using static probes with mechanical heads, while the second will include methods based on measurements using static probes with electrical heads.
