Embodiment Construction

[0031] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings.

[0032] Near Gudong, Daxu Town, Guilin City, Guangxi Zhuang Autonomous Region, the typical water-land ecotone of the Li River was selected to divide the water-land ecotone. Its main steps are:

[0033] 1. Selection of environmental factors: Select environmental factors based on the spatial distribution structure characteristics of the Lijiang River-land ecotone; the water-land ecotone is disturbed by seasonal floods and presents a relatively special spatial distribution structure, so it should be based on the particularity and factors of the water-land ecotone. Applicability, multi-level and dominance select environmental factors, and the water-land ecotone is different from other structural types, and the factor selection has particularity, such as hydrological influence time, while the ap...

Abstract

The invention discloses a dividing method for a land and water ectone. The method includes steps of selecting environmental factors based on space distribution structure characteristics of a land and water ectone of a to-be-analyzed spot; collecting environmental factor data and performing data analysis; performing clustering analysis based on data analysis results and dividing land and water ectone. The method is a dividing method of a strip type parallel to river flow direction, so that scientific researchers can develop scientific study according to ecological degradation characteristics of different strips and perform vegetation recovery development in a manner of adjusting measures to local conditions, so that basis is provided for ecological recovery of degraded land and water ectone.

Description

technical field [0001] The invention belongs to the field of vegetation restoration and water and soil conservation, and relates to a method for classifying and dividing water and land ecotones in alternate wet and dry environments, specifically a method for dividing water and land ecotones suitable for river ecological degradation in karst areas. Background technique [0002] The water-land ecotone, also known as the shore zone, waterfront zone, river bank (coast) zone, and ebb and flow (fluctuation) zone, is an important biological transition zone for the exchange of energy, matter and information between aquatic ecosystems and terrestrial ecosystems. The division of land and water ecotones at home and abroad is usually guaranteed by RS and 3S technology, combined with field site condition investigations, and classified according to site characteristic factors. The existing division methods mainly include: dividing by the specific structure of the water-land ecotone, groun...
