Research On Suitability And Optimize For Planting Mainly Fruit Trees Of Hebei Taihang Mountain Area

Our country is a mountainous country, the development of mountain agriculture is an important part of China’s agricultural development, rational development of mountain areas can contribute to the comprehensive development of mountainous areas of social and economic. Hebei Taihang Mountain area, due to the fragile ecological environment, drought, soil is thin, poor soil fertility, soil erosion and serious reasons, their agricultural development is limited, only to find out the plants need to grow habitat conditions, constraints, full use of mountain resources to promote sustainable development of agriculture. Fruit industry is one of the main industries in the Taihang Mountains, suitability and optimal layout conduct research in this area is mainly fruit trees, fruit trees can be Taihang Mountain Area rational exploitation of resources, the agricultural structure adjustment provides a scientific basis.Fruit tree planting suitability evaluation, based on growing conditions for fruit growing needs, constraints, through superposition and evaluation to determine the most suitable for the cultivation of fruit trees area, so as to optimize the layout of the area of fruit trees. According to the main fruit Taihang suitability factors, local conditions to develop a more rational, scientific planning, to optimize the industrial structure and layout. In this paper, the principle of adaptability evaluation of fruit trees, contents and evaluation methods to make a more detailed exposition of Map Info and Arc GIS geographic information system software for a brief introduction, and developed a TAIHANG main fruit and optimal layout Suitability Study technical route.In this paper, the Taihang Mountains area is mainly for the study of fruit trees, its suitability and optimal layout study. By combining existing data queries and to consult experts, and ultimately determine the 10 Taihang Mountain area main elements of the suitability of fruit trees and fruit trees according to the size of the growth impact of its sort, calculate the suitability factors AHP weights under the guidance of experts were graded on each element of the suitability criteria and scoring. Then, using geographic information system software for organic matter, light, accumulated temperature, precipitation and other elements of the suitability of 10 basic maps are superimposed to generate major fruit trees suitable for planting range chart, and then generate the main fruit tree planting suitability evaluation map. Taihang Mountain area of the main fruit grown Suitability Evaluation show: Apple graded as suitable for planting the most appropriate, suitable, more appropriate, accounting for a percentage of the total area of the Taihang Mountains 12.8%, 16.5%, 4.5%; suitable for planting pear classified as the most suitable, appropriate more appropriate, accounting for a percentage of the total area of the Taihang Mountains 12.8%, 16.5%, 4.5%; persimmon cultivation suitability classification percentage of the total area of Taihang accounted 12.8%, 16.8%, 5.5%; walnut planting suitable grade for the most appropriate, Suitable, more appropriate, accounting for a percentage of the total area of the Taihang Mountains 10.7%, 10.2%, 3.3%; jujube cultivation of suitable grade for the most suitable, suitable, more appropriate, accounting for a percentage of the total area of the Taihang Mountains 16.9%, 14%, 4.9%. By evaluated graphs to analyze the suitability of Taihang five main fruit growing distribution and rules for agricultural planning and optimization of Taihang Mountains Taihang Mountain area fruit industry development layout put forward feasible suggestions, but also provide the basis for the adjustment of agricultural structure and management of the Taihang Mountain area.
