Problems solved by technology

[0004] However, the traditional large-scale afforestation of barren hills has a long cycle and unreasonable planning and design of afforestation; the selection of afforestation tree species is unreasonable and has not been adapted to local conditions; improper tending measures have resulted in low tree survival rates

Embodiment Construction

[0019] Taking the large-scale afforestation of barren hills in Loufan, Shanxi as an example, a kind of large-scale barren hills afforestation method based on GIS of the present invention comprises:

[0020] (1) Small class selection and site type division

[0021] Based on the "one map" of forest resources in Loufan County, Taiyuan City, and the data from the Second National Land Survey, the land types suitable for afforestation were selected: suitable forest land, forest land without standing trees, and shrub land (with low-efficiency shrub land transformed into arbor forest) etc. Excluding dry land, irrigated land, urban residential land, rural homestead, cultivated land, orchard, etc. The selected small classes will analyze and investigate the dominant environmental factors (topography, soil, vegetation, slope, slope aspect, etc.) and conduct comprehensive analysis. Based on the principle that the internal conditions of the site type tend to be consistent, but there are ob...

Abstract

The invention discloses a GIS (Geographic Information System)-based large-scale barren mountain afforestation method. The method comprises the following steps: (1) subcompartment selection and site type division; (2) selecting tree species; (3) determining the afforestation density; (4) preparing a mixing proportion; and (5) afforestation technical measures. According to the method, the GIS space planning and analysis technology, the ecological system succession law and the near-natural management theory are utilized, the problem of regional large-scale barren mountain afforestation is solved, the optimal barren mountain afforestation mode is achieved, the greening rate is increased, the afforestation area and forest coverage rate are increased, and sustainable forest development is achieved.

Description

1. Technical field [0001] The invention relates to the technical field of ecological protection and restoration, in particular to a GIS-based large-scale barren hill afforestation method. [0002] 2. Technical Background [0003] With the rapid development of social economy, the global ecological environment continues to deteriorate, and soil erosion in mountainous areas is becoming more and more serious, which has caused immeasurable losses to regional economic development and ecological security. In recent years, the state has vigorously promoted policies such as returning farmland to forests and afforestation, which has improved the quality of the ecological environment in the region. Afforestation on barren hills can play a role in water conservation, soil and water conservation, windbreak and sand fixation, and is one of the best solutions to promote the rapid development of the natural environment and reduce regional soil and water loss. To a certain extent, it can grea...
