Abstract

The authors present the results of a geoinformation analysis of the fields system and protective forest plantations in the Serafimovichi district, the Volgograd oblast, RF. The degree of protecting forest reclamation from degradation in agricultural landscapes was established, and the plantations safety was estimated. Employing geoinformation technologies enables accelerating the assessment of the agroforestry systems state. Anthropogenic and climatic factors affect the conditions of their functioning. At the same time, the geoinformation analysis of agroforestry landscapes based on ultra-high-resolution satellite images by the WorldView 3 satellite of the MAXAR provider allows us to identify their current state. The methodology is based on a landscape approach, and the technology - on using GIS to decrypt satellite images and determining the spatial characteristics of fields and protective forest plantations. Maps of cultivated and uncultivated lands and their safety were developed from satellite images. It is established that agricultural landscapes include 2,101 fields (189,5 thousand ha), 1,765 of which are cultivated (181,4 thousand hectares) and 336 are deposits (8,1 thousand hectares). There are 1,272 plots located on deflation-risk areas tilted by less than 2°. In potentially erosive ones with steepness of more than 2° there are 829. The spatial position of the fields and the safety of 2030 protective forest stands are determined

农林景观空间特征的地理信息分析

作者介绍了对俄罗斯联邦伏尔加格勒州谢拉菲莫维奇地区的田地系统和防护林种植进行地理信息分析的结果。研究人员确定了农业景观中防止森林退化的防护林开垦程度，并对人工林的安全性进行了估算。利用地理信息技术可以加快对农林系统状态的评估。人为因素和气候因素影响着农林系统的运行状况。同时，根据 MAXAR 提供商的 WorldView 3 卫星拍摄的超高分辨率卫星图像对农林景观进行地理信息分析，可以确定其现状。该方法以景观方法为基础，技术则是利用地理信息系统解密卫星图像，确定田地和防护林种植园的空间特征。根据卫星图像绘制了耕地和非耕地及其安全地图。农业景观包括 2 101 块田地（18.95 万公顷），其中 1 765 块为耕地（18.14 万公顷），336 块为洼地（8.1 万公顷）。有 1 272 块土地位于倾斜度小于 2° 的通货紧缩危险区。陡度超过 2° 的潜在侵蚀地块有 829 块。田地的空间位置和 2030 个防护林带的安全性已确定
