Transport development bring a negative impact on human survival ecological environment, such as destruction of vegetation, air pollution, soil erosion and other environmental issues. The actuality proves that the use of tunnel development of underground space can improve traffic quality, while also protecting the environment. Therefore, tunnel engineering and utilization of underground space are to protect the ecological environment to be effective ways for realizing economic sustainable development of economy. In this paper, based on the practical application at home and abroad, for the big cities, mountain areas, river waters, the suitability evaluation and beneficial discussion about the transportation by using tunnel to protect the ecological environment are of great practical significance to protect and improve the ecological environment.

AbstractLand consolidation procedures are an attempt to comprehensively change the existing spatial structure of land in rural areas. This treatment also brings many other social and economic benefi ts, contributing to the development of consolidated areas. Land consolidation in mountain areas differs in many respects from those implemented in areas with more favorable conditions for the functioning of agriculture. The unfavorable values of land fragmentation indices, terrain conditions and lower than the average soil quality affect both the dominant forms of agricultural activity and the limited opportunities to improve the distribution of plots in space, parameters of shape, and the area as a result of land consolidation. For this reason, the effectiveness of land consolidation in mountain areas can be achieved by improving the quality of transportation network and the accessibility of the plots, arranging ownership issues and improving the quality of cadastral documentation. This article presents the evaluation of the measures of effectiveness of land consolidation realized in mountain areas on the example of Łetownia Village in the Małopolska Province, located in the southern part of Poland. Selected village is an area with unfavorable conditions for the functioning of agriculture and high values of land fragmentation indices.

The study's objective was to characterize the soils and carry out suitability evaluation of floodplain soils in Ardo-Kola, Taraba State. Six (6) profile pits were dug from two physiographic units and the most predominant land use (woodland area and arable land area). Three (3) profile pits were dug on each of the identified units using standard dimension. Soil morphological results indicated that the soils were sub-angular blocky, strong to fine structure, very sticky, hard when dry and firm when moist in the woodland area. Colour ranged from pale brown 10YR (6/3) to dark greyish brown 10YR (4/2). Soils in the arable land area were mostly very sticky, firm when moist and hard when dried. The colour ranged from light yellowish-brown 10YR (6/4) to dark grey 10YR (4/1). Results of particle size distribution were sandy loamy and loamy sand across the pedons. Bulk density values ranged from 1.50 to 1.67gm/cm3, and total porosity ranged from 37 to 43% respectively. The soils were generally moderately acidic to slightly acidic, organic carbon and total nitrogen was low (<2% and <0.15%), calcium and magnesium were rated medium (2-5cmol/kg and 0.3-1.0cmol/kg) respectively. Base saturation values were rated medium (50-80%) to high (>80%) across the pedons. Soil suitability result for the woodland area showed overall suitability for maize in pedon BYF1 was S3w (marginally suitable) with limitation in nutrient availability and suitable (S1) in pedon BYF5. Arable land area was also marginally suitable (S3) with limitation in oxygen availability except for pedon BYF4, which was not suitable (N) for maize cultivation. Woodland area was moderately suitable (S2) and suitable (S1) for the arable land area with limitation in texture except for pedon BYF 3 with limitation in oxygen availability. Rice production is encouraged in the arable land area while maize in the woodland area using fertilizers and organic materials to ameliorate low fertility limitations observed in the study area.

The aim of the study is to study the possibility of obtaining agricultural products from dry lands in arid climatic conditions of mountain areas, depending on natural moisture availability. The concept of types of arable land locations was introduced. The entire variety of locations of arable land in the Sanaa basin is divided into five types of locations depending on the location of a particular one or another form and relief element. The characteristics of the types of locations of the main wadi, intermountain basin, plain and other forms of relief of the Sanaa basin are given. The methodology for assessing the natural moisture availability of the types of locations of arable land of the main landforms was developed. Based on the materials of experimental field work on drain-forming sites and literary sources, the values of the runoff coefficients of the exits of indigenous rocks, loose eluvial, deluvial-proluvial and alluvial sediments of arable lands were determined and adopted for the calculation of natural moisture availability.

AbstractIn the present study Cervatana and Almagra models from decision support system, MicroLEIS DSS, were applied to segregation of arable land surfaces from the marginal ones and suitability evaluation of wheat (Triticum aestivum), maize (Zea mays) and alfalfa (Medicago sativa) in Souma area with approximately 4100 ha extension in West Azarbaijan. Obtained results from both models are presented and discussed in this research work. Soil morphological and analytical data were collected from 35 soil profiles, representative of the study area and stored in SDBm plus database. The control or vertical section of soil for applying and running the models for annual selected crops, was calculated by soil layer generator 0.0–50 cm in depth, or between the surface and the limit of useful depth when the latter is between 0.0 and 50 cm. According to results, 80.49% of the total area was good capable for agricultural uses and 19.51% must be reforested and not dedicated to agriculture. The lands with good capability for agricultural uses is classified as highly suitable area (S2) for wheat, maize and alfalfa, but results in 822 ha for maize and in 126 ha for alfalfa refers to an excellent suitable (S1) and moderately suitable (S3) classes respectively. The most important limitation factors are soil texture and carbonate alone or together and maize — wheat — alfalfa can be selected as the best crop rotation. A simple map subsystem (ArcView GIS) was used for basic data and models result demonstration on a map.

Changes in the cultural landscape provide essential evidence about the manner and intensity of the interactions between humans and nature. Czechia has a specific location in Central Europe. It is positioned at the crossroads of European landscape changes. These changes can be documented based on a unique database that shows the development of land use since the middle of the 19th century. In this study, we aimed to address the major processes of landscape change that occurred during four periods over the past 165 years, at the cadastral level on the territory of present-day Czechia. Further we identify and discuss proximate and underlying driving forces of the landscape changes. We used land use data from the year 1845, 1896, 1948, 1990, and 2010 that correspond to key events in Czech history. The major processes and intensity of landscape change were evaluated based on calculations of increases and decreases in land use classes between the first and last year of each examined period. The period 1845–1896 was the only period in which arable land increased, and the most recent period, 1990–2010, was the only period during which a grassing over process was recorded. Afforestation was recorded in all periods. The communist period was characterized by unified changes—urbanization, afforestation, arable land decrease, and landscape devastation. The post-communist period was, in some respects, beneficial to the landscape (e.g., grassing over and afforestation, particularly in mountain areas), but it also led to negative processes, such as strong urbanization and land abandonment. Such changes lead to landscape polarization. The landscape changes in Czechia during the period 1845–2010 reflect many important historical events in Europe. In our analysis, we demonstrate the essential impact of underlying drivers and also identify driving forces specific to the development of the Czech territory.
