Problems solved by technology

[0005] At present, ecological migration, western development, great opening up, and great protection all involve subjective evaluation of the hardships of the natural environment, but there is a lack of systematic and quantitative quantitative analysis and evaluation of topography and geomorphology, which is not conducive to land space planning and natural resource development. Precise implementation of work such as utilization, ecological environment protection and restoration

Abstract

The invention discloses a landform condition measurement method and device. The method comprises the following steps that: a measurement and calculation model about landform condition measurement is established; geographic national condition monitoring data are extracted and preprocessed; a target area is determined, the target area is divided to form a plurality of subareas, and according to the geographic national condition monitoring data, each index factor and parameter thereof in the measurement and calculation model of each subarea are calculated; and according to each index factor and the parameter thereof, a topographic and geomorphic condition measurement value of each subarea is calculated, wherein the topographic and geomorphic condition measurement value is used for evaluating livable degree of each subarea in the aspect of topographic and geomorphic conditions. The method can make full use of existing geographical condition monitoring data, and scientifically, objectively, efficiently and quantitatively analyze the relative conditions of landforms of all regions from the perspective of human production and life livability.

Description

technical field [0001] The invention relates to the technical field of geographic information processing, in particular to a method and device for measuring terrain and geomorphic conditions. Background technique [0002] Human beings and the natural environment are interdependent and utilize each other, and human beings are not only the creators of the environment, but also the creators of the environment. Atmosphere, water body, soil and biological world are the four natural environmental elements on which human beings depend, and they are inextricably linked with topography. [0003] High altitude is often accompanied by low pressure, low oxygen, cold, dryness, and strong ultraviolet rays. The rocky surface and lack of soil in the area greatly increase the difficulty of natural vegetation reproduction and artificial cultivation. Surface undulations, slopes, and slope aspects have a profound impact on agricultural production. Flat surfaces are conducive to mechanical oper...
