In this study, the trends of the climate station belonging to the Turkish General Directorate of Meteorology in the center of Nevsehir province of Turkey between 2001-2019 years were subjected to the Rho’s correlation tests of Mann Kendall and Sperman for years of maximum open surface evaporation and total open surface evaporation. According to the results of the trend analysis, the maximum open surface evaporation was 59,7 mm and the total open surface evaporation was calculated as 1013,2 mm in the center of Nevsehir Province over long period. It was observed that the average maximum temperature value was 24 oC for long years and the total precipitation average was 363,6 mm. It was observed that there was a significant increase in open surface evaporation values varying in years in spring, winter and autumn. According to the trend analysis results made for many years, a trend was not observed in the Maximum and total open surface evaporation parameters in Nevsehir province of Turkey

In this study, land use capabilities, land types and other soil properties of Kırşehir province were classified and analyzed. In the study, 1/25.000 scale digital soil maps obtained from the Ministry of Agriculture and Forestry (Turkey) were used. Numerical data were classified using Arc GIS 10.3.1 software, which is one of the GIS software. As a result of the research; In general, It was observed that IV. class lands were formed in the Kirsehir province IV.class lands were found to be 1658.3 km2 and it was determined that they cover 25% of the total area. It is seen that soil insufficiency is high in Kırşehir province due to slope and erosion damage. Soil insufficiency due to slope and erosion damage was found to be 3520.7 km2 and it was determined that 54% of the total area was exposed to this effect. It has been observed that the land type is generally composed of steppe, bare rocks and rubble. It was determined that the area formed by bare, rocks and debris is 1128.5 km2. It has been determined that the stony soil areas are 1094.2 km2. As a result of the study, classified map outputs related to land uses and some soil properties were obtained. It will be inevitable that this research will provide important database bases for other studies to be carried out in this region in the future.

This study was carried out to determine the spatial distribution of land slopes, soil depths, erosion classes, large soil groups and some soil properties by using Geography Information Systems (GIS) in Kayseri province (Turkey). As a result of the spatial analysis distributions; It has been observed that a large part of the province of Kayseri consists of soils with a depth of C class (50-90 m), and this area covers an area of 9443.95 km 2 . It is seen that the areas belonging to the E class (0-20 m) soil depth group are very few and this soil depth class covers an area of 6.50 km 2 . When the spatial analysis results of soil slope classes are examined, it is seen that the largest surface area is between 3-6% slope and this area is 8022.80 km 2 . It has been determined that the areas in the 30-45% slope class have the smallest surface area and the total of these areas is 5.21 km 2 . In terms of erosion classification, the lands in Kayseri province are classified as II. classified as areas of high erosion risk. When evaluated in terms of large soil groups, it has been determined that generally limeless brown soils are dominant and the total amount of these areas is 6156.54 km 2 . It has been determined that the area covered by brown forest soils has a very small share in the whole area. Considering other soil properties, it was determined that slightly salty soils cover a very small area (0.99 km 2 ). It has been determined that stony soils cover an area of 8600.58 km 2 . As a result of the study, spatial distribution maps were created showing soil depth, slope and erosion classes, large soil groups and other soil characteristics of Kayseri province, which will guide the investor organizations in the region.

In this research, the total and maximum precipitation values of long years (1970-2019) of Nevşehir province, Ürgüp districts and 34 years of Avanos 1986-2019 were subjected to the Mann Kendall and Sperman's Rho rank correlation tests. In this study; Change trends of the precipitation are presented with graphic distrubitions. According to the results of the trend analysis, it has been observed that the average maximum precipitation value for long years in Avanos district, Nevsehir Province and Ürgüp district is 9,1 mm, 11,3 mm, 10,7 mm and average total precipitation is 292,8 mm, 362,9 mm, 326,9 mm respectively. According to the results of maximum precipitation trends, it has been observed that there is a significant increase in Nevşehir province and Ürgüp districts in winter and autumn months. Considering the total precipitation distribution, it is concluded that there is a negative trend in the spring and autumn seasons in Nevşehir province and Ürgüp district.
