Restoring the quake­hit ecosystems is a question of balancing the interests of the local people and the environment. Rural methane (沼气) projects can reduce the number of locals taking firewood from the mountainsides. The use of straw as food for animals will ensure that vegetation(草木) can grow. In Sihai township and Dazhuangke village, in Beijing, they now have a forestry coverage of 85% or more, compared to the 30% they had 15 years ago. Back then, land was used very inefficiently: one person would use 20 mu of forest just for firewood. With those pressures on the ecosystem, no amount of spending on reforestation will succeed. Then the government relocated the population and paid those who remained to tend the forest and provide coal. This reduced the pressures on the ecosystem and it was able to recover naturally.

When an ecosystem has not been pushed past certain limits, it is able to recover on its own. Human involvement should only play a minor role, including after an earthquake. This is particularly the case for sandy grasslands, grasslands deserts, the mountains of the south and the northern sides of mountains in the north. In these areas soil remains and the water, light, heat and nutrients needed are available. Less human involvement is even more appropriate in areas with a small population, where it can avoid money being wasted on ineffective efforts, such as creating forests in dry areas.

The creation of nature reserves should be a model to allow damaged ecosystems to recover. Funding can start at the national level; centrally­funded nature reserves can enforce environmental protection laws and help to promote the local economy. This will solve the problems of reserves being run to make money. When national reserves are funded, local governments will be able to adopt the same model and provide the funds for nature reserves from their own budgets. The first project should be established in nature reserves hit by the quake; these can then become models for other areas.

（5）业主供料价款在发生当月的工程款中扣回。

（6）若施工单位每月实际完成的产值不足计划产值的90%时，业主可按实际完成产值的8%的比例扣留工程进度款，在工程竣工结算时将扣留的工程进度款退还施工单位。

施工计划和实际完成产值表 单位：万元

该工程施工进入第四个月时，由于业主资金出现困难，合同被迫终止。为此，施工单位提出以下费用赔偿要求：
