本文研究主旨在於（1）运用地理资讯系统建立校园属性资料，并以此功能辅助后续研究之用；（2）利用地景结构指数探讨中兴大学校园的变迁过程；（3）以马可夫链机率向量的基本原理与概念，配合地理资讯系统之相关技术，探讨校园土地利用型之地景结构与变化，（4）配合以时间历程为考量的半马可夫链，来推测未来校园土地利用於稳定状态下所需的分配比例。

With the development of civilization, peoples demand became more and more , land, as an important product stuff ,the intensity of landuse became higher and higher ,as the result: the quantity of farmland decreasing ; average area of tilth deducing ; urban expanding ; in land structure table ,built-up land ascending ,farmland and non-used land declining .

经济的发展，人类社会的进步，人的需求不断的得到满足，土地作为一项重要的生产要素，其利用结构也随之发生着变化：耕地总量的减少，人均耕地面积的下降，城市的扩张，土地利用结构表中，建设用地比例的上升，农用地和未利用地比例的下降等等。

The results indicated that (1) the economy in Zhejiang Province was in the developing stage of unchanged scale wage;(2) the inputoutput elasticity coefficients was the most sensitive to labour element among the factors which had effect of economic growth in Zhejiang Province.The results showed that the coefficient was 0.538 5 in labour element while the coefficients were 0.247 3 in land element and 0.321 6 in fixed asset elements respectively;（3）the contribution of the input of fixed assets was 6823% and still the major impetus to economic growth during this time;(4)the land use was not intensive basically in Zhejiang Province,the input of land elements was replaced by that of other elements during the study.So,labour intensive industry should be one of the industries in the future.

研究结果表明：(1)就规模效应而言，浙江省的经济增长处于规模报酬不变的发展阶段；(2)浙江省经济增长对劳动力要素的投入最为敏感，其中土地要素、劳动力要素和资本要素增加1个单位的投入量对经济增长的推动为 0.247 3、0.538 5 和 0.321 6；（3）固定资产投入在研究期间是浙江省经济增长的主要推动力，其贡献率达到6823%，而劳动力要素与土地要素则分别为2346%和625%；(4)浙江省土地利用不够集约，在研究期间土地要素对经济增长的影响能被资本要素与劳动力要素有效替代，而劳动力要素则难以被资本投入与土地投入有效替代，劳动集约型产业应该成为浙江省未来发展方向之一。
