【摘要】 以信息熵原理分析了垦利县土地利用的分异规律。结果显示:垦利县土地利用结构信息熵在1986-2003年期间有几次波动:1986-1990年基本保持不变,但保持较高水平(0.6961),1990年之后逐渐收敛,1993年达到最小值(0.6862),之后逐步升高,至2002年达到最大(0.6965),之后略有下降并趋稳定。信息熵在空间的分布以东部沿海的红光办事处和市畜禽场的信息熵最小,而垦利县城及以西地区,包括垦利镇、高盖乡和胜坨乡的信息熵较大。根据同期的社会经济数据,分析了影响信息熵变化因素,并建立信息熵变化模型。更多还原

【Abstract】 This paper analyses the differentiation law of land utilization in Kenli County on the principle of information entropy,with the result that there were several fluctuations in the information entropy of land use structure in Kenli county from 1986 to 2003: remaining basically stable in the period of 1986-1990 with a high-level(0.6961);descending gradually since 1990,reaching the minimum in 1993(0.6862);rising again later,reaching maximum in 2002(0.6965),slightly dropping later and becoming steady.As to the spatial distribution of information entropy,it was the smallest at Hongguang office and poultry field along east coast,while the greatest at the town proper of Kenli and the west area.Based on the social economic data of the same term,this paper analyses the factors that influenced the information entropy,and sets up models of information entropy change.更多还原
