新疆沙雅县土地利用规划战略环境评价

随着全国性、地区性土地利用规划的制定与实施，探讨适合于土地利用总体规划环境影响评价的技术方法具有重要意义.采用战略环境评价理论，以生态系统服务价值为评价指标，对新疆沙雅县1996—2010年土地利用规划可能带来的生态环境影响进行了综合评价.结果表明：1996—2010年间，沙雅县生态系统服务价值从1996年的69.33×10⁸元增加到2010年的70.81×10⁸元，其年增长率为0.15%.规划期间，研究区土地利用变化导致的生态系统服务价值变化呈增加趋势，表明该规划基本合理，但需要加强对社会用地等方面的控制；该区生态价值的增长速率高于其GDP的增长速率，属于生态价值盈利地区，但该规划还存在一些不足，如未利用地（荒漠）面积的比例到2010年将达到83.95%，故应对此规划进行完善和修改，以提高土地利用的生态效益.

Strategic environmental assessment on land use programming of Shaya County, Xinjiang Uygur Automous Region.

With the establishment and implement of national and regional land use programming, to approach the technology and methodology of environmental assessment appropriate for the overall land use programming is of great significance. By using the theories of strategic environmental assessment and taking ecosystem services value as an evaluation index, a comprehensive assessment on the potential eco-environmental effects of 1996〖KG-*2〗-〖KG-*7〗2010 land use programming of Shaya County in Xinjiang Uygur Automous Region was made. The results showed that from 1996 to 2010, the total ecosystem services value of the County increased from 6933×108 Yuan to 7081×108 Yuan, with an annual increment of 015%, which suggested that this programming was basically reasonable. However, the common land expansion should be controlled strictly. The increase rate of eco-value was higher than that of GDP, indicating that Shaya County was of eco-value gaining. There were still some shortages in the programming, e. g., the area ratio of unutilized land (desert) would be 8395% in 2010, and thus, the programming should be emended to increase the eco-benefit of land use.
