Intelligent evaluation method for suitability of forest and grass in land parcels

Abstract

The method mainly aims at effectively improving the quality of forest resources and solving the problem of unbalanced distribution of the forest resources, the invention provides the intelligent evaluation method for the suitability of the land parcels and the forest and grass, which is combined with data of forest resource distribution, meteorological conditions, landforms, soil, climate and the like to explore new development of the suitable land and suitable trees in China, so as to improve the adaptability of the land parcels and the forest and grass. The spatial distribution characteristics of main tree species groups in China are explored, the distribution suitability is evaluated from longitude, latitude and altitude ranges, and the nationwide planning of the land parcel forest and grass suitability is completed by using big data, smart phones, artificial intelligence and data mining.

Description

1. Technical field [0001] The invention relates to an intelligent evaluation method for planning the suitability of forests and grasses in national plots based on 3S, smart phone, meteorological big data, terrain, soil, vegetation and other data. [0002] 2. Technical background [0003] The distribution of forests is the result of the interaction between the environment (abiotic and biotic) and plants. The growth environment of trees includes factors such as climate, topography, soil, vegetation, and water. Different site conditions make plants use different water and nutrients, thus indirectly affecting the growth and development of vegetation. Site conditions include factors such as aspect, slope, slope position, elevation, and soil thickness, each of which has a different effect on tree growth. The growth of trees is not only affected by their own size and site conditions, but also closely related to climate factors. Climate is an important factor in determining the dist...

Problems solved by technology

[0005] At present, China is still a country that lacks forests and greenery and is ecologically fragile. The forest coverage rate is far below the global average level of 31%, the per capita forest area is only 1 / 4 of the world average level, and the per capita forest stock is only 1 / 3 of the world level 7. In the face of problems such as insufficient total forest resources, low quality, and uneven distribution of my country's forest resources have not been fundamentally changed, and it is difficult to meet the new requirements of economic and social development and the new expectations of the people. Exploration is particularly important
