摘要

影响安塞实验区水土保持经济效益的主要因素是人口数量、副业收入、水土保持状况和农林牧业用地面积等。用灰色模型GM(1

1)的预测结果说明。实验区的每人平均总产值在1986—2001年将以4.2%的年增长率稳步发展;关联度的分析结果指出

每人平均总产值同生产力、副业收入、林业用地面积、水土保持状况和牧业用地面积成正相关

同农业用地面积成负相关。要使实验区的总产值或每人平均总产值达到最大

必须增加生产力和提高人口素质

大力发展副业

使林业用地面积占可用地面积的百分数不少于30%

农地占可用地面积的25%左右

使农林牧副等生产结构趋于合理化。

Abstract

The main factors influencing development of agricultural economy in experimental area of soil and water conservation in Ansai county are population

soil and water conservation level

land area of agriculture

forertry

animal husbandry

and income from sideline occupations

etc. The total value of production each will increase steadily at the annual rate of 4.2% during 1986-2001

as GM (1

1) forecasted

and is directly related to population

income from sideline accupation forest land area

soil and water conservation level

and animal husbandry land area，but negatively related to agricultural land area

as the analysis of the relativity shows. To maximize the total value of production of agricultural economy or the total average value of production each in the experimental areas

the productive forces must be improved

condition of sideline occupation be developed greatly

forest land area must not be less than 3000 of whole arable land，the agricultural land area should be about 25% of whole arable land

so as to optimize the production structure of agriculture

forest

animal husbandry

sidqline etc
