Base on comparison with the remote sensing data in 1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland, river-way and water area, salinised land, town, Gobi, shift sand dune, denudative upland. The results show that,(1) there were obvious changes in land cover structure.

By the cooperation of 8-MOP/UVA, the photoaging-characteristic biological markers of the dermic fibroblasts in vivo and in intro were changed as follows:① with a permanent switch of mitotic to stably postmitotic phentypes, fibroblasts displayed growth suppression and morphological changes of cell senescence;② increasing expression of SA-β-galactosidase;③ increasing expression of p16 protein;④ continuous up-regulation of mRNA of MMP-1 and MMP-3, while the protein of TIMP-1 was only slightly induced;⑤ high levels of the 4977bp deleted mtDNA accumulated in dermis and cultured fibroblasts, and large accumulation of a A→C base transversion of 414 position of 〓 of human mtDNA control region for replication of cultured fibroblasts also.

2.8-MOP/UVA作用下，体内外真皮成纤维细胞生物学特性出现具有光老化特征性的改变：①细胞由具有分裂活性的分裂表型转化为不具有分裂能力的分裂后表型，形态学出现细胞衰老的相应改变；②SA-β-Gal表达增加；③p16蛋白表达增加；④MMP-1、MMP-3 mRNA持续表达而TIMP蛋白表达仅被轻微诱导；⑤mtDNA 4977bp缺失大量累积，培养成纤维细胞mtDNA复制控制区〓片段414碱基迅速出现大量A→C的点突变。
