通过研究中国退耕还林还草的现状及问题，指出由于退耕区域布局缺少严密的科学论证，监督检查没有科学的评价体系，致使政策效果大打折扣；退耕补偿政策的不合理、不公平性以及退耕地未来收益的不确定性，又使退耕还林还草成果巩固面临潜在威胁。

Soil moisture content varied abruptly in the ecotone zone, hut presented linear distribution in both grassland zone and farmland zone. The average soil moisture content in grassland was about 1 gg^(-1) higher than that in farmland, which was mainly caused by the decreased capillary moisture capacity of farmland.

其中农田－草地复合功能区的土壤含水量变化剧烈，而草地功能区与农田功能区内土壤水分基本呈线性分布；草地生态系统土壤平均含水量比农田高约1 gg^(-1)，这主要是由于草地开垦为农田后风蚀等作用而引起的土壤毛管持水力下降所致。

In natural vegetation area, where mainly are forest land, the yearly relative humidity and precipitation of spring are the driving forces to the change of NDVI. In brush and shrub area, the change of NDVI is driven by the precipitation and relative humidity of autumn. In grassland and rare tree bush grassland district, the main driving forces are human factors, and the driving mechanism is that farmland and cropping sown area are negative to the change of NDVI, but society factors are positive.

对于以林地为主的自然植被区植被覆盖变化，主要受到春季降水、春季湿度和年均湿度的正驱动，黄淮海地区的北部主要为干旱、半干旱区，因此春季降水偏多会利于植被生长；灌丛和萌生矮林区，秋季降水和秋季湿度对其植被NDVI变化呈负驱动；草原和稀树灌木草原区植被覆盖的变化，耕地面积、作物播种面积对之为负驱动，而其他社会经济因子则为正驱动。

In order to find the vegetable niche pattern in arid and semi-arid grassland region, the niche breadth and niche overlapping in Yanchi county of Ningxia in 2006 and 2007 are measured by means of Levins niche breadth and Pianka niche overlapping indexes in the enclosed grassland.

运用Levins生态宽度指数及Pianka生态位重叠指数，对宁夏盐池人工封育草原2006年和2007年植物生态位宽度及生态位重叠进行计量，以了解干旱半干旱区草原植物生态位格局。

Above 90% of the area of grassland is degraded and the degraded area is increasing more and more. Although the degradation is contained by the control measures to certain degree, there are still some problems such as property right restriction, difficulty in supervision, unitary policy and neglect of herdsmen's income, for this reason, the view of livestock reduction subsidy is presented. Subsidy of 50 Yuan for one sheep or goat is given to herdsman's family, 600 Yuan for one cattle; meanwhile 200kg grains is given to every one of the herdsman's family for fuel subsidy, standard culture plot construction subsidy, livestock insurance subsidy to make sure that herdsman's income is increased while the grassland is protected.

我国90%以上的草原已退化，并且还在不断扩大，虽然采取的治理措施在一定程度上遏制了草原退化，但产权制约、监理执法困难、政策手段单一以及忽视牧民增收还是目前退化草原治理过程中存在的问题，为此提出减畜补贴的观点：给予小牲畜50元／只、大牲畜600元／头的直接补贴，同时给减畜牧户家庭每人200kg基本生活口粮和燃料补贴、标准化规模养殖小区建设补贴和灾害保险补贴，做到在保护草原生态的同时促进牧民增收。

In recent years, the county up and down firmly establish the "animal husbandry instability instability in the whole county, not the rich herders, the county is not rich" ideas, has always been to increase efficiency of agriculture and animal husbandry, farmers and herdsmen in rural incomes and maintain stability as the work of farmers and village enterprise, has invested 2,480 million yuan to build one or two bases and livestock disaster insurance camel, cashmere goats base, completed the demonstration county animal husbandry and the "three" of training works, the new on the restoration and protection of natural vegetation projects, ban works, the completion of 3 million mu of artificial grass, aqueduct built five more than eighty kilometers, 22 kilometers of flood control dams, the new hit 12 motor-pumped wells, construction of the drug bath, flood pool 20, the completion of fencing 41.7 million mu of grassland, built to high standards SHELTER 20, control the "three" of 57.7 million mu of grassland, improved herd face up to 82%, the proportion of school-age dams more than 56%.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
