The results indicated:(1)the combination of the Markov and spatial logistic models can improve the predictability of each model individually. In macroscopic scale, the total land use amount can be predicted via Markov chain; in microscopic scale, the multi-class multinomial logistic model can be used to implement the combined calculations of categorical variable and continuous variable, qualitative variable and quantitative variable to improve the precision of spatial regression. Meanwhile, the transition probability of each land use unit will be confirmed and the prediction of land use spatial distribution will also be completed.(2)the application system developed in accordance with the integrated model can effectively simulate and predict the land use evolution in Shenzhen City, and the prediction precision of verification system will suffice for recent land use monitoring and the making of annual land supply planning.

The allelic diversity in terms of number of alleles per locus and expected heterozygosities in cultured populations N=8.0-9.4, H(subscript e=0.754-0.787 was considerably lower than that found in the wild populations N=11.3-15.0, H(subscript e=0.821-0.866. Allele distributions at all seven microsatellites indicated that the cultured populations lost some rare alleles belonging to wild populations. The small number and the biased sex ratio of abalone for hatchery broodstock might be responsible for the remarkable reduction of genetic variation in the studied populations.
结果表明,从等位基因数与杂合度上分析,养殖群体(N=8.0~9.4, H=0.754~0.787)遗传多样性显著低于野生群体N=11.3~15.0, H(下标 e=0.821~0.866;等位基因频率分布揭示出野生群体中一些稀有等位基因在养殖群体中有所丢失;亲鲍选用数量少与性别比例不均衡可能是产生养殖群体中遗传多样性显著减少的原因。
