The paper aims to illustrate the key growth stages of olive and the relationship between botanical characteristics and meteorological variables. In Wudu mountain, the botanical characteristics of olive and the meteorological observation data from 2012 to 2015 were collected. Based on the leading indicator of average temperature in January and several other factors such as annual average temperature, annual average relative humidity, and annual sunshine hours, an olive suitable climate division index system was built for Wudu mountain. The fine climate division map for olive cultivation suitability was made by applying GIS technology. The results indicated that: the most suitable olive planting areas were located in the valley plains, basins, and shallow mountainous areas below the elevation of 1300 m in the southern Wudu and Bailong river basin; suitable olive planting areas were located in the valley plains, basins, and shallow mountainous areas in the elevation of 1400- 1500 m; the other areas were unsuitable for olive growing which were mainly in the northwest Wudu and other places above the elevation of 1500 m. The results can guide scientific planning and rational arrangement for Wudu mountain and make the best of climate resources to develop olive industry, and also provide a scientific basis for prevention and mitigation of meteorological disasters.

The study of spatial and temporal distribution characteristics of the water requirement of crop could provide the basis for effective utilization of water resources and rational distribution of crop. Based on the meteorological data and phenological data from 13 stations of irrigation district in Ningxia Hui Autonomous Regions, ETC of main crops (spring wheat, maize, rice and winter wheat) in the whole growing period and at different growth stages during 1961 to 2010 were estimated by using FAO Penman-Monteith equation and corrected crop coefficient, and the spatial and temporal distribution characteristics of ETC were analyzed，then the irrigation requirement and water requirement rate of main crops during the growing season were analyzed. Results showed that effective precipitation showed a slightly decreasing trend in the whole growing period of rice and maize and showed a slightly increasing trend in the whole growing period of spring wheat and winter wheat. The effective precipitation of autumn grain crops was two times as much as that of summer grain crops during 1961-2010. The high value areas of effective precipitation were in Shitanjing, Lingwu and Zhongning, and the area with low effective precipitation was in Shizuishan. The order of crop water requirement in the whole growing period was rice>maize > winter wheat > spring wheat, the distribution of water requirement was similar to the irrigation requirement during each growth stage. The water requirement and irrigation requirement showed a remarkably increasing trend in the whole growing period and each growth stage, the values of high water requirement and irrigation requirement were observed in each station of Shizuishan and Zhongning. Water requirement rate significantly increased after jointing (striking root), the water requirement rate reached the maximum value at anthesis-milk stage of spring wheat and winter spring wheat and jointing-anthesis and anthesis-milk stages of maize, the water requirement rate was maintaining at a high level after jointing and reached the maximum value at milk - mature stage.

The impacts of human production and life on land use in mountainous area mainly focus on settlement ecological niches, taking the settlement ecological niche as the basic research element could effectively reveal the changing process of land use in micro-scale in mountainous area and the action mechanism between human and land. Temporal-spatial distribution and change characteristics of land use in the dry valley settlement ecological niche of the upper reaches of Min River from 1999 to 2009 were studied based on remote materials and Geographical Information System technology. The results showed that: (1) the farmland areas in the settlement ecological niche significantly decreased during the ten years, but the grassland and forest areas increased; (2) the land use in the settlement ecological niche was concentrated within the altitude range of 2001-2900 m and the gradient of 15o-35o, and the land use area of the south slope was higher than that of the north slope, and the land use area of the east slope was higher than that of the west slope; (3) the land use structure in high mountainous area in the settlement ecological niche tended to be well-aligned, but the land use structure in low-high mountainous area tended to have a disorder state. The land use in the settlement ecological niche in the upper reaches of Min River was in a quick adjustment stage, the farmland showed obvious non-agricultural characteristics, such as farmland changing to grassland, ecological forest and economic fruit forest. The main reason was attributed to the joint action of population decrease, ecological conservation policies and comparative benefits.

In order to evaluate rural tourism development in Xinxiang and analyze its influencing factors, establish a comprehensive evaluation system for development modes of rural tourism, and weigh the advantages and disadvantages of different modes, five development modes of rural tourism, namely rural scenery type, red tourism type, modern new country type, agricultural resources type and natural scenery type, were classified according to their development themes. A comprehensive evaluation was carried out using analytic hierarchy process (AHP) and fuzzy evaluation method in terms of infrastructure construction, tourism resource exploitation and tourism operation and management. Results showed that the comprehensive evaluation value of natural scenery type was 0.82 out of 1.00, which was the highest. The outstanding performance of natural scenery type was mainly driven by rural environmental construction, natural resource exploitation, local investment environment, year-end profit of enterprises and satisfaction degree of tourists. Thus the authors suggested that natural scenery type should be preferentially developed in the rural tourism industries of Xinxiang. Among all the evaluated indexes, the year-end profit of enterprises was with the largest weight coefficient of 13.1%, indicating that it was an important index to evaluate the sustainable development of a scenery spot. The evaluation method developed by the authors is an innovative one which can significantly simplify the quantification of indexes, and rule out the subjectivity in weight coefficient estimation.

Ecological security can be explained from broad-sense and narrow-sense. Since the wider area and regional discrepancy in influenced factors and eco-background, the regional environment hasn’t been studied systematily. The paper built the Stress-response-regulation model according to the interaction between human and environment, and analysis the safety degree of west part of Jilin province in 2000 using compound model and Grid method based on GIS and RS. The results show that most part of the study area belong to the security state while the risk and non security area distributed in the middle and west part of the study area, furthermore, the state of east is better than that of west. When talk about ten counties of the region, absolute security account for a very small quantity, and the county that has widest area of security is Qian’an while the smallest is Da’’an. Tao’nan is the county that the area of risk is biggest, 43.08 percent of whole county area and the that of Qian’an is smallest, accounting for 1.56 percent only. The area of non security of Tongyu, zhenglai and Da’an have exceeded 10 percent and been the urgently treatmented region. Coupling between ecological security and type of land use showed that the farm belt is relatively stable while pasturing area has been distroied furthest. Although the value of grass is more than that of farmland by the Constanz’s theory of ecological value, the cover degree of grass in study is lower and when there is disturbance, whole system lost balance.
