摘要

退耕还林(草)工程对吴起县农业生态经济系统演变态势产生了重要影响。该县收入结构由1990年的种植业:畜牧业:工副业:林业为31.5:7:10.5:1;演变为2006年的3.4:3.2:3.4:1;土地利用结构由1999的耕地:林地:人工草地为1:2:5调整为2006年的1:14:10。在上述分析的基础上

选择人口、种植业收入、林业收入、畜牧业收入、工副业收入、人均纯收入、粮食单产和森林覆盖率等8个指标

运用聚类分析方法

探讨了吴起县农业生态经济系统的演变阶段:1990-1996为第二阶段初期

1997-2002为第二阶段中后期

2003-2006为第三阶段初期。针对目前存在的现实问题

为了进一步促进农业生态经济系统的良性互动

实现农业资源与产业的优化耦合

需要调整林分结构

发展林草及其相关产业

对劳动力进行技能培训

增加劳务输出。

Abstract

The project of converting slope farmland into forest and grassland has greatly influenced evolutionary trend in the agricultural eco2economic system of Wuqi County.The income structure of crop farming:animal husbandry∶parergon∶forestry changed from 31.5∶7∶10.5∶1 in 1990 to 3.4∶3.2∶3.4∶1 in 2006.The landuse structure of cultivated land ∶forest land ∶artificial grassland evolved from 1∶2∶5 in 1999 to 1∶14∶10 in 2006.Based on the above result

the 8 indexes of population

crop farming income

forestry income

animal husbandry income

industry income

per capita net income

yield of grain

and forest coverage were chosen.Cluster analysis method was used for the discussion on the evolvement stage of agricultural eco2economic system of Wuqi County.Results show that 1990 - 1996 was the incipient stage of the second stage ; 1997 - 2002 was the mid2latter of the second stage ; and 2003 - 2006 was the initial stage of the third stage.In view of the existing problems

it is necessary to adjust forest structure

develop forest (grass)and related industries

train labor service

and increase labor output for the purposes of promoting the sound interaction in the agricultural eco2economic system and realizing agricultural resources and industrial optimization coupling.
