Embodiment

[0093] A method for determining the adaptive scale of agricultural development and utilization of sandy land in the sandstone area of ​​the present invention, such as figure 1 As shown, the specific steps are as follows:

[0094] Step 1, calculate the water resource constraint threshold;

[0095] Taking Yuyang District of Yulin City as a typical demonstration area for research; Yuyang District of Yulin City is located in the north-central part of Yulin City, Shaanxi Province, on the middle reaches of the Wuding River, adjacent to Shenmu in the east, bordering on Inner Mongolia in the northwest, and Jiaxian County and Mizhi County in the southeast Handover; Yuyang District is located in the hinterland of the Mu Us Sandy Land, about 30km north of the Great Wall; there are a large number of arsenic sandstone and sand widely distributed around the area, which is a typical wind-sand grass beach area;

[0096] Taking 2013 as the current year, collect and analyze the basic data of w...

Abstract

The invention discloses a determination method for a sandy land agricultural development and utilization adaptability scale of a sandstone area. The method comprises the steps of firstly calculating awater resource constraint threshold in the area; secondly according to three objective functions of economic benefits, social benefits and ecologic benefits, establishing constraint conditions; thirdly building a multi-objective optimization model, and setting multiple situation schemes meeting different planting structures; and finally solving the multiple situation schemes of the different planting structures, and determining the sandy land agricultural development adaptability scale and an optimal planting structure. The method solves the problem of water resource shortage in a sandy landagricultural development and utilization process of the sandstone area, facilitates sustainable utilization of water and land resources in a development area, and promotes a virtuous circle of ecological environment in the area.

Description

technical field [0001] The invention belongs to the technical field of sandy land agricultural development, and in particular relates to a method for determining the adaptive scale of sandy land agricultural development and utilization in arsenic sandstone areas. Background technique [0002] The total area of ​​desertified land in my country is about 1.721 million square kilometers, accounting for 17.9% of the country's land area. The productivity of desertified land areas is low and the ecological environment is fragile. Among them, the arsenic sandstone distributed in the sandy land has a total area of ​​about 16,700 square kilometers, mainly concentrated on both sides of the Yellow River in the bordering areas of Shanxi, Shaanxi and Mongolia. Due to its low degree of diagenesis, poor cementation between sand grains, and low structural strength, it forms mud when it meets water. , When encountering wind-generated sand, water and soil loss is very serious. At the same time...
